Probably I am biased by seeing way to many of this "narcissistic spiritualism" which is nothing but another way of boosting the ego, while one of the cornerstones of Buddhism is to get rid of notions of "I", "soul" and "mine" or, at least, to diminish them to the point of language idioms, given that it is known since Upanishads, that there is no "I" or "myself" apart of a environmental and social conditioning, plus conditioning by personal experiences, related to your social niche (a cast). That's why this is an issue for me.
