Yoga Sutra I-51 - TASYAPI NIRODHE SARVA NIRODHAN NIRBIJAH SAMADHI - When even this impression is wiped out, every impression is totally wiped out and there is nirbija [seedless] samadhi.
Swami Satchidananda states in his commentary for this sutra that it is only now at this point that Patanjali describes the highest samadhi. "Even with the ritambhara prajna the subtle mind is there. There is still a division between the prajna, or wisdom, and the owner of tha wisdom. Even the feeling, 'I have realized God' should go. Then you are completely free. You have attained nirbija samadhi. There is no more birth or death for you; you realize your immortality."
