I want to explorer masturbation in this text.
Word of warning.
1. Buddhism advocate refraining from sensual pleasures. So you are about to read a text that is NOT buddhism.
2. This is NOT an instruction on howto get a better orgasm. Quite the opposite.

Most of the text is from the Indian guru Osho.

Once in a while I had the urge to masturbate. But it was becoming a problem for me. I would always become a little depressed the day after. And when I became aware of it, I remembered my wife once noted that I often was moody or grumpy the day after sex with her.
I started thinking deeply on this behaviour and I realized that I felt a deep longing when my mood took a dive the day after. There were also a strong feeling of loneliness. For a long time i could not get deeper in the understanding of this.

You will discover that sex is not what you are looking for, it is closeness. To your self. Your thoughts may have been fractured, and you feel incoherent. Your thoughts may be all over the place. You need to come back to your self. To be in a fetal position again. Holding another person intimately is a spiritual thing more than a physical thing. Holding your self or another is the same. It is both mental formations. It is a deep felt safety.

Truly good sex dissolves your self-sense. The boundary between you and you partner dissapears. You become one. Sex is true intimacy with self.

Here follows some text that may inspire you. At the end is a guide to masturbating. Imagine that. “Oh my, isn’t my hands going to fall of, or I will go blind?”

Vigyan Bhairav Tantra – Meditation Technique 50

Once you know this, even the partner is not needed. You can simply remember the act and enter into it. But first you must have the feeling. If you know the feeling, you can enter into the act without the partner. This is a little difficult, but it happens. And unless it happens, you go on being dependent, a dependency is created.

For so many reasons it happens. If you have had the feeling, if you have known the moment when you were not there but only a vibrating energy had become one and there was a circle with the partner, in that moment there was no partner. In that moment only you are, and for the partner you are not: only he or she is. That oneness is centered within you; the partner is no more there. And it is easier for women to have this feeling because they are always making love with closed eyes.

During this technique, it is good if you have your eyes closed. Then only an inner feeling of a circle, only an inner feeling of oneness, is there. Then just remember it. Close your eyes; lie down as if you are with your partner. Just remember and start feeling it. Your body will begin to shake and vibrate. Allow it! Forget completely that the other is not there. Move as if the other is present. Only in the beginning is it “as if.” Once you know, then it is not “as if,” then the other is there.

Move as if you are actually going into the love act. Do whatsoever you would have done with your partner. Scream, move, shake. Soon the circle will be there, and this circle is miraculous. Soon you will feel that the circle is created, but now this circle is not created with a man and woman. If you are man, then the whole universe has become woman; if you are woman, then the whole universe has become man. Now you are in a deep communion with the existence itself, and the door, the other, is no more there.

The other is simply a door. While making love to a woman, you are really making love to existence itself. The woman is just a door, the man is just a door. The other is just a door for the whole, but you are in such a hurry you never feel it. If you remain in communion, in deep embrace for hours together, you will forget the other and the other will just become an extension of the whole. Once this technique is known you can use it alone, and when you can use it alone it gives you a new freedom — freedom from the other.

It really happens that the whole existence becomes the other — your beloved, your lover — and then this technique can be used continuously, and one can remain in constant communion with the existence. And then you can do it in other dimensions also. Walking in the morning, you can do it. Then you are in communion with the air, with the rising sun and the stars and the trees. Staring at the stars in the night, you can do it. Looking at the moon, you can do it. You can be in the sex act with the whole universe once you know how it happens.

But it is good to start with human beings because they are nearest to you — the nearest part of the universe. But they are dispensable. You can take a jump and forget the door completely — “EVEN REMEMBERING UNION, THE TRANSFORMATION” — and you WILL be transformed, you will become new.

Tantra uses sex as a vehicle. It is energy; it can be used as a vehicle. It can transform you, and it can give you transcendental states. But as we are using sex, it looks difficult for us — because we are using it in a very wrong way, and the wrong way is not natural. Even animals are better than us: they are using it in a natural way. Our ways are perverted. Constant hammering on the human mind that sex is sin has created a deep barrier within you. You never allow yourself a total let-go.

Something is always standing aloof condemning, even for the new generation. They may say they are not burdened, obsessed, that sex is not a taboo for them, but you cannot unburden your unconscious so easily. It has been built over centuries and centuries; the whole human past is there. So while you may not be condemning it as sin consciously, the unconscious is there constantly condemning it. You are never totally in it. Something is always left out. That left-out part creates the split.

Tantra says move in it totally. Just forget yourself, your civilization, your religion, your culture, your ideology. Forget everything. Just move in the sex act: move in it totally; do not leave anything out. Become absolutely non-thinking. Only then does the awareness happen that you have become one with someone. And this feeling of oneness can then be detached from the partner and it can be used with the whole universe. You can be in a sex act with a tree, with the moon, with anything. Once, you know how to create this circle, it can be created with anything — even without anything.

You can create this circle within yourself because man is both man and woman, and woman is both woman and man. You are both because you were created by two, You were created by man and woman both, so half of you remains the other. You can forget everything completely, and the circle can be created within you. Once the circle is created within you — your man is meeting your woman, the inner woman is meeting the inner man — you are in an embrace within yourself. And only when this circle is created is real celibacy attained. Otherwise all celibacies are just perversions, and then they create their own problems. When this circle is created inside, you are freed.

This is what tantra says: “Sex is the deepest bondage, yet it can be used as a vehicle for the highest freedom.” Tantra says poison can be used as medicine, but wisdom is needed. So do not condemn anything. Rather, use it. And do not be against anything. Find out ways how it can be used and transformed. Tantra is a deep, total acceptance of life. It is the only approach of its kind. All over the world, in all the centuries that have gone by, tantra is unique. It says don’t throw anything and don’t be against anything and don’t create any conflict, because with any conflict you will be destructive with yourself.

All the religions are against sex, afraid of it, because it is such a great energy. Once you are in it you are no more, and then the current will take you anywhere. That is why the fear. So create a barrier in which you and the current become two, and do not allow this vital energy to have any possession over you: be the master of it.

Only tantra says that this mastery is going to be false, diseased, pathological, because you cannot really be divided with this current. You are it! So all divisions will be false, arbitrary, and basically, no division is possible because you are the current — a part and parcel of it, just a wave in it. You can become frozen and you can separate yourself from the current, but that frozenness will be deadness. And humanity has become dead. No one is really alive; you are just dead weights floating in the stream. Melt!

Tantra says try to melt. Do not become like icebergs: melt and become one with the river. Becoming one with the river, feeling one with the river, merging in the river, be aware and there will be transformation. There IS transformation. Transformation is not through conflict; it is through awareness. These three techniques are very, very scientific, but then sex becomes something other than what you know. Then it is not a temporary relief; then it is not throwing energy out. Then there is no end to it. It becomes a meditative circle.

Osho on witnessing sex and anger energy – Circle of sex energy is the strength of a Buddha

You have to concentrate not on the cause outside, but on the source inside. Forget the cause. Close your eyes, and go deep and dig into the source. Then you can use the same energy which was to be wasted on someone outside – the energy moves inwards.
Take another example. You are feeling sexual: sex is again energy, fire. But whenever you feel sexual, again you are focused on someone outside, not on the source. you begin to think of someone – of the lover, of the beloved, A-B-C-D – but when you are filled with sex your focus is always on the other. You are dissipating energy.
Not only in the sexual act do you dissipate energy, but in sexual thinking you dissipate it even more because a sexual act is a momentary thing. It comes to a peak, the energy is released, and you are thrown back. But sexual thinking can continuously be there. You can continue it in sexual thinking, you can dissipate energy. And everyone is dissipating energy. Ninety percent of our thinking is sexual. Whatsoever you are doing outside, inside sex is a constant concern – you may not even be aware of it.
You are sitting in a room and a woman enters: your posture changes suddenly. Your spine is moire erect, your breathing changes, your blood pressure is different. You may not be aware at all of what has happened, but your whole body has reacted sexually. you were a different person when the woman was not there; now again you are a different person.
An all-male group is a different group, and all-female group is a different group. Let one male come in or one female, and the whole group, the whole energy pattern, changes suddenly. You may not be conscious of it, but when your mind is focused on someone, your energy begins to flow. when you feel sexual, look at the source, not at the cause – remember this.
Science is more concerned with the cause and religion is more concerned with the source. The source is always inside; the cause is always outside. With cause you are in a chain reaction. With cause you are connected with your environment. With source you are connected with yourself. So remember this. This is the purest method to change unconscious energy into conscious energy.
Take an about-turn – look inside! It is going to be difficult because our look has become fixed. We are like a person whose neck is paralyzed, and who cannot move and look back. Our eyes have become fixed. We have been looking outside for lives together – for millennia – so we don’t know how to look inside.

Be concerned with from where the sex desire has come in. Follow it, take steps backwards. Meditate silently and go with sex to the roots. It is difficult but it is not impossible. It is not easy. It is not going to be easy because it is a fight against a long, rooted habit. The whole past has to be broken, and you have to do something new which you have never done before. It is just the weight of sheer habit which will create the difficulty. But try it, and then you are creating a new direction for energy to move.

You are beginning to be a circle, and in a circle energy is never dissipated.
My energy comes up and moves outside – it can never become a circle now; it is simply dissipated. If my movement inwards is there, then the same energy which was going out turns upon itself. My meditation leads this energy back to the same source from where the anger was coming. It becomes a circle. This inner circle is the strength of a Mahavir. The sex energy, not moving to someone else, moves back to its own source. This circle of sex energy is the strength of a Buddha.

We are weaklings, not because we have less energy than a Buddha: we have the same quanta of energy, everyone is born with the same energy quanta, but we are accustomed to dissipating it. It simply moves away from us and never comes back. It cannot come back! Once it is out of you, it can never come back – it is beyond you.
A word arises in me: I speak it out; it has flown away. It is not going to come back to me, and the energy that was used in producing it, that was used in throwing it away, is dissipated. A word arises in me: I don’t throw it out; I remain silent. Then the word moves and moves and moves, and falls into the original source again. The energy has been reconsumed.
Silence is energy. Brahmacharya is energy. Not to be angry is energy. But this is not suppression. If you suppress anger, you have used energy again. Don’t suppress – observe and follow. don’t fight – just move backwards with the sex. This is the purest method of awareness.

Osho, The Psychology of the Esoteric, Talk #3

Create Meditation Out of Sex

“The more you go into meditation through sex, the less effect sex will have. Meditation will grow from it, and out of the growing meditation a new door will open and sexwill wither away. It will not be a sublimation. It will be just like dry leaves falling from a tree. The tree never even knows the leaves are falling. In the same way, you will never even know that the mechanical urge for sex is going.

“Create meditation out of sex; make sex an object of meditation. Treat it as a temple and you will transcend it and be transformed. Then sex will not be there, but there will not be any suppression, any sublimation. Sex will just become irrelevant, meaningless. You have grown beyond it. It makes no sense to you now.

“It is just like a child growing up. Now toys are meaningless. He has not sublimated anything; he has not suppressed anything. He has just grown up; he has become mature. Toys are meaningless now. They are childish and now the child is no longer a child.

“In the same way, the more you meditate, the less sex will have an appeal to you. And by and by, spontaneously, without a conscious effort to sublimate sex, energy will have a new source to flow to. The same energy that has flowed through sex will now flow through meditation. And when it flows through meditation, the divine door is being opened.”

Exercise for sex with your self

Start by taking a shower. Put on perfume if you like. Set a side 1 hour for this.
Draw the curtains so you feel absolutely private. Lay on the bed or the sofa.
Start with just breathing and feeling your naked body. Let awareness move around your body.

Then start to caress your self where it feels good. Some may feel embarrassed by touching places that is not strictly your genitals. Feel awkward, like when we were kids and kissed our selfs in the mirror. If so then touch where you feel confortable. Later in this session you may feel it is okay to broaden the area as your self awareness dissolves and you are more focused on the touching.

Important! You will most likely be focusing on your genitals, in your mind. On the subject of ejaculating or reaching the climax. On imagining some sex partner, or some fantasy intercourse. This is to be avoided! If this is going to be anything more then simple masturbation you must avoid thinking about anything external to your self. Focus on the touching. Avoid your penis or inside of your vagina. All other areas are good. The destination is not to reach climax. It is to stay with the very powerful energy of the sexual feeling itself. Forget the orgasm.

After maybe 15 minutes, you should be more susceptible to exploring other areas of your body. No place is forbidden except the place that will give you orgasm. Don’t be afraid, open up. When you really get into it, touching your self will not feel any different then touching your fiancee. There is only touching.

Remind your self that you set aside 1 hour for this, so there is lots of time. Some time during this session you will start to feel bore, or your thought will start to wander. Or get tired. Then just do that. Get bored or tired. Let thoughts wander. Your mind is fickle. In 5 more minutes the touch will be inviting again. Continue.

After a long time, maybe an hour or sooner you will start to feel filled up. That you have gotten what you yearn for. Most probably you have succumbed to the orgasm. The “happy end”. If so don’t be hard on your self. It is not important. If you did not succumb then spend the rest of the day being aware of how different you feel in your body. You may also feel a little frustrated, all depending on your personal situation. Most probably it will take several sessions to get the insight needed to transcend the orgasm.

After some trial and error you will probably get a whole new type of experience when ever you feel lonely, or when you think of your self, or touch your self.
