"Normal" is a very subjective judgment defined by each society or subculture based upon social norms and values. Ram Das is someone worth understanding, even if you don't buy into his version of reality. If you understand him it will open your mind. If your mind is shut you won't understand, or even take the time to try.

Truthfully, I doubt I'd take the time to read his whole book if I came across it today. But the time I spent reading it years ago was worthwhile and enlightening.
