An indulgence of sensual pleasures associated with mind-consciousness is a bad thing. Sure, it may be seen as a better thing than indulgence of any of the other senses. However, imagination and manipulation of the perception of the mind might be just as destructive as any other sensual indulgence.
Playing around with one's mind is a dangerous thing. In my experience, few people realize that it is such a bad idea. And the experiences that come from that sort of practice always seem to me to produce unskillful states of mind. I hope that for my own sake and the sake of others that, through my beings, others might also be able to calm down and see the world with clarity.
