Osho The AH AHA AHOO Meditation
Osho - Hold the hands in a very prayerful mood and start a mantra 'Ah... ah... ah', loudly, but not very loudly. And move with that 'Ah... ah... ah'; move with it. Do it for just five to seven minutes not more than that. Just before you go to sleep, sit in your bed and just bring the energy out.
Move very slowly, very gracefully; don't become violent. That's why I am saying not more than five or seven minutes, because if you do it more, you will become more and more agitated, and then the prayer will be lost.
After seven days, be in the same posture but change the sound 'Ah' to 'Aha'. That will go still deeper -- 'Aha... aha... aha'. After fifteen days tell me how you are feeling. First 'Ah' for seven days, and the 'Aha' for seven days. The sound 'Aha' can give tremendous grace.
God happens as an 'Aha' experience. God is not a proposition but an exclamation. So you start. The energy is going very well. Prayer will be helpful... and this is your prayer, nothing else.
[Osho further has added another stage to this meditation.] " After five minutes of saying 'ah!' then a further five minutes of saying 'aha!', Osho said to add a further five minutes of 'ahoo!', saying ...
The English language is acquainted with the two -- 'ah!' and 'aha!' 'Ahoo' is not part of the English language, but that is the third step in the same series of sounds. It is a state of gratitude, of thanksgiving. 'Ah' creates silence, 'Aha!' creates joy, and 'Ahoo' starts giving thanks and expressing gratitude. [Osho also said it would be helpful to burn incense through the meditation ...]
Use the same incense every night. That enters into your bio-memory and it starts triggering things. So just burn the same incense every night, and never bum that incense at other times, otherwise you will lose track. Let it be associated only with this meditation.
