A broad term embracing a number of techniques for achieving various altered states of awareness, with some of these altered states resulting in the ecstatic qualities of so-called “peak experience;” most meditative techniques are ways of learning to still the agitation of the mind so that more subtle and valuable aspects of self and reality may be perceived; some techniques involve concentration, in which attention is focused on a particular object and restrained from wandering, while others involve giving one’s total attention to whatever spontaneously happens, with no attempt to control or focus attention.
