Lama Ole’s answer:
There must really be a ring and hook there. I am from the sixties and had a lot of experience with drugs. I wrote my exams at the University of Copenhagen, and before I met Buddhism I was very interested in all possibilities for unfolding the mind.
OK, the clear light that one sees on LSD is really great, or being able to leave one’s body and all of that. But gradually you discover that it’s actually not the drugs that make you happy. The happiness that you might have experienced in half a year gets compressed into eight hours. When you have done that a few times, at some point the red letters come from the bank, “Overdrawn! Overdrawn!” and the joy and meaning are gone—fear and confusion take their place.
If you have taken drugs, then that is the background you can work with. You then develop yourself further through meditation, which lays a foundation for everything beyond that. But if you haven’t taken drugs, you don’t need to do it now.
I am not saying that LSD should not be used. It should be available for psychologists to use in cases of extreme fear of death. Actually, in such cases, minimal doses of 25 micrograms can make a “click” so that the fear disappears. I think that LSD should be available as a tool—as medicine—in the hands of good psychologists, perhaps also lamas if they have the time. But it should not simply be available for everyone to stuff their heads with. That is not good. And if you achieve development without drugs, if you succeed with your own strength through meditation, it is much more effective. You establish something permanent. If you take drugs, first you’re way up and then you crash again; you have a lot of yo-yo trips that you can gab about later, but you have no lasting experience. With meditation, you put one stone on top of the other. Wherever you are in your development—that’s where you really are.
