raman,
“without cleaning yourself you can not attain samadhi, and so you can not awaken your kundali power.”
That is simply the borrowed nonsense that you have imported into your mind. If you were speaking out of one’s own scientific exploration, you would not have said such a thing. If you mean by “cleaning yourself” the practice of purification of the body through kriyas, then it is not really the case. One can experience samadhi without all of those techniques of purification of the body. All of those methods were just created as aids to help the transition into meditation. One can sit immediately for meditation without all of those preperations - but one will have to deal with the same obstacles directly through the mind without the aid of the body.
As far as samadhi is concerned, it may be almost impossible to believe, but the average person has already experienced samadhi several times before - although they may not have been aware of it in the moment because they were not alert. If you are sitting in a resteraunt and a waiter walks by and drops the plates - shattering them, just from the shock for a brief moment or two, the activity of the mind has come to a cessation, and you are in a state of pure consciousness. Or, if you are entering into a forest, and you think you are safe and secluded, and suddenly you become attacked by a wild animal - again, just briefly, just from the shock the activity of the mind has become still - and you are in a state of pure awareness. Like this, there are many instances where samadhi does arise, although one fails to recognize it because one is not paying attention. Usually it happens when one is shocked spontaneously - because in such moments the mind breaks free of it’s ordinary habitual patterns. That is why in Zen, the master will strike the disciple at the right moment with the right understanding. It is not out of violence - it is to bring into your perception the same experience, and experiments have shown that millions of disciples have become enlightened through such methods.
As far as awakening of Kundalini is concerned, there are many ways besides just kriyas - some of which involve methods which are even more dangerous than the ones which are ordinarily practiced. And sometimes, without any practice, one can experience a Kundalini awakening - although it is a rare event.
Drop all of this dogmatism as to how things should be done. In the spiritual sciences, there are as many different methods and approaches as one can conceive, all a finger pointing to the moon.
