Meditation can open the mind to a similar range of conscious states, but far less haphazardly. If LSD is like being strapped to a rocket, learning to meditate is like gently raising a sail. Yes, it is possible, even with guidance, to wind up someplace terrifying, and some people probably shouldn’t spend long periods in intensive practice. But the general effect of meditation training is of settling ever more fully into one’s own skin and suffering less there.
