Self-knowledge through drug-use???

Jiddu Krishnamurti quote

Q: I think it is possible under certain drugs to know myself with analysis - there is no conflict.

K: If one takes LSD or various forms of drugs that helps a great deal, because in that there is not conflict at all. So you please take drugs. Does it really, does any drug, LSD, marijuana, any of them - does it really expose the totality of the content of consciousness, or does it bring about chemically a certain state of mind which is totally different from the understanding of oneself? These drugs - I have never taken them - they have taken them in India a great deal - I watched many people there. I have also watched students in universities in America, and many, many other people who have been taking various forms of drugs, LSD, marijuana, you know I don't know what all the other names are - psychedelic drugs. If you have observed, these drugs do affect the mind, the brain cells themselves. They destroy the brain. If you have talked to one or many of those who have taken drugs, they can't reason, they can't pursue a logical sequence of thought - and the doctors and the scientists are beginning to say it does destroy the very structure of the brain cells. Not only LSD but marijuana, which is much more dangerous than LSD because that leaves a toxic condition in the brain cells and is more difficult to get rid of. In India they have taken drugs for millions, for thousands of years and they are the most ignorant people who have taken drugs. And all the so-called intellectuals in India have denied it, said don't do it, touch it. I am not asking you not to take it, it's up to you, but when you see the effect of it, on people - they have no sense of responsibility, they think they can do anything they like, many, many hospitals are full of these people who mentally are unbalanced through drugs.

Q: I find your sequence of thought illogical. And also I cannot see how you can argue against drugs if you have not any experience of taking drugs.
K: Ah wait. How can you argue against drugs if you have not taken drugs yourself? Must you go through various forms of experience, must you get drunk in order to understand sobriety? Must you get angry in order to find out what it is not to be angry? Must you over eat in order - and so on and so on. Can't one observe without going through all the human mischief?
