According to Osho, the roar of 'Hoo' rides on breath, which permeates every pore; thus the sound reverberates not just in the heart or navel but throughout the body, striking sexuality that is concentrated at the sex center yet diffused everywhere. This forceful sonic 'hammering' cracks the inner seed, freeing virya (sex-energy) to rise upward, catalyzing deeper meditation.
Shouting “Hoo” strongly sends vibrations with your breath through your whole body, hits the sex energy, and helps it move upward into calm awareness.
From the Discourses
Passages where Osho speaks to this question — each links to the complete discourse.
That friend has also asked: Osho, if you say we should bid farewell to old cows, then tomorrow might it not come to having to bid farewell to an old father or an old mother as well!
It can happen. And if you keep producing too many children, it will happen. This is a very harsh truth. It is very sad. But perhaps no other path will remain. Just as today we retire a man at fifty-five or fifty-eight from his job. Why do we do that? So that the children coming up behind can get work; otherwise they won’t. It is not necessary that a fifty-five-year-old is no longer fit to work. In truth, removing an experienced fifty-five-year-old from work and giving that work to an inexperienced twenty-year-old is economically a loss, not a gain. But it is a compulsion. The fifty-five-year-old has to be set aside; otherwise how will the children get work? As the situation worsens further, it may not be only retirement from jobs; we may have to decide that a person of sixty-five or seventy must retire from life. The responsibility for…
Many have spoken of renunciation—of leaving wealth, house, home, loved ones, family. I ask you only to drop misery. Only drop sorrow. And if you are willing to give me your suffering, I am ready to give you bliss. It can happen this very moment. If the second stage is complete, you will become like an empty vessel—no more scum, no dust collected. Or like a mirror we have cleansed of the dust of ages—now a reflection can arise—pure, pristine. If the second stage remains incomplete, you will not enter the third. Each leap occurs only from completeness. When the second stage completes, only then are you at the peak from which you can jump into the third. Each stage is a necessary link. If even one remains incomplete, you will be stuck there. And this second is difficult, because the first was only breathing.
Beloved Osho, will you please indicate something about the fifth stage in active meditation.
Do not do anything. You are not going to die! Even if the sneeze is coming and you do not sneeze for ten minutes, you will not die. If you feel like coughing, if you feel an irritation in the throat and you do not do anything, you are not going to die. Do not be afraid: no one has ever died. Remain DEAD as far as the body is concerned so that the energy can move in one flow. When the energy moves upward you become more and more silent. Silence is the by-product of energy moving upward and tension is the by-product of energy moving downward. You will be more and more in anxiety when energy moves down; you will be more and more silent, quiet, calm and cool as energy moves upward and inward. And these words downward and outward are synonymous, and inward and upward are…
Hatha Yoga tries to bring the energy upward. Raja Yoga tries to free you from thoughts. Both travel in the same direction. Hatha Yoga's concern is that the energy should come upward; therefore there is Shirshasana, there are mudras by which the energy can be pulled upward; there are bandhas by which energy can be drawn upward. Hatha Yoga does not concern itself with thoughts. It says, the energy will come upward and thoughts will be destroyed by themselves. Raja Yoga does not concern itself with energy. It says, if thoughts become silent, energy will of itself come upward. Both are joint events. One can begin from anywhere. If your trust is very much in the body, then Hatha Yoga is the path for you. And if your trust is more in the mind, then Raja Yoga is the path for you.
If you have heard about Chinese acupuncture you will be able to understand it more easily. They say that vital energy flows in the body, and there are points in the body, eight hundred points, from where that energy can be contacted. When you are ill, it means that a particular contact point in the body has become nonfunctioning; it is not in contact with the universal energy. The contact has to be made again, it has to be renewed. By pushing or stroking or massaging or inserting pins into that small point of energy to make it alive, a particular disease will disappear. According to acupuncture, every disease comes because you are not in contact with the universal energy around you; the contact is missing. Just like blood circulates, subtle energy, your vitality, circulates in the body. I ask you to jump.
