It is only if bondage is real that liberation and the nature of its experiences have to be considered. So far as the SELF (Purusha) is concerned it has really no bondage in any of the four states. As bondage is merely a verbal assumption according to emphatic proclamation of the Vedanta system, how can the question of Liberation ,which depends upon the question of bondage , arise when there is no bondage? Without knowing this truth, to enquire into the nature of bondage and Liberation , is like enquiring into the non-existent height, color , etc of a barren woman's son or the horns of a hare.
