In the preceding sutras many types of experience were described. As these are encountered, the yogi goes ever deeper into the levels of their own being. Each is encountered, explored, experienced, and set aside, so as to go still deeper. Finally comes the finest of the levels of individuality, the sattvic buddhi. (3.50)

Here, in this sutra, one not only experiences the discrimination between the subtlest aspect of mind and consciousness itself (purusha), this distinction becomes well established.

When that subtle-most distinction has happened, and is well established, there comes mastery over all forms or states of existence, as well as over all forms of knowing.

When even this finest distinction between sattvic buddhi and purusha is set aside (1.15, 3.38), there comes absolute realization or kaivalya, stated in next expisodes sutra(3.51).

According to Raja yoga, kaivalya is the final stage of enlightenment that a yogi can reach, also called moksha or nirvana. In this state, the yogi becomes completely fearless and free. Although it is sometimes wrongly perceived as negation or annihilation, kaivalya is a state of total awareness.
