The author has sought to remove a confusion regarding the state of liberation, (which is the avowed goal of indian philosophy), Arising from a failure to distinguish between two states both called 'samadhi.' in one sense, 'samadhi' is a state of deep contemplation wherein the mind is made to concentrate on a particular object, To the exclusion of all other thoughts. Another state, Called 'nirvikalpa samadhi,' comes into being when the mind is perfectly silent, Yet watchful and sensitive, Without any (...) effort to concentrate. This state of liberation remains ever undisturbed by whatever one does on the psycho-Biological plane. (shrink)
