Patanjali's Yoga Sutras tell us that reality may be sought along two paths: (a) Discrimination, which would be an obstacle on the other path; but leading only to a limited relative insight tethering consciousness to a seed or "kernel of bondage"; (b) the other path on which, as A.J. Van Leeuwen says, "No-seed samadhi leads to perfect freedom." Van Leeuwen significantly adds: "Then the search is at an end, because the seer has discerned its uselessness. He comes to rest and finds nirvanic peace between the wings of the mystic swan Kalahamsa. When he brings his I-thought to rest by destroying his attachment to the I-ness (which is something else than ceasing to think as is tried to achieve in contemplation, and entirely different from petrifaction of the mind by concentration), then the opposites melt together. Be-ness has been attained, freewill has become the same as fate, freedom and law have become identical, drop and ocean enter each other, thesis and antithesis are cancelled out and sublimated into synthesis."
