Krishna describes the final, victorious culmination of this multi-life process. But (tu) when that Yogi continually strives and endeavors with massive, intense effort (prayatnād yatamānas), they become entirely washed, purified, and scrubbed clean of all sins and karmic dirt (saṃśuddha-kilbiṣaḥ). Having accumulated and achieved perfection over the course of many, many lifetimes (aneka-janma-saṃsiddhas), it is from that point (tato) that the Yogi finally reaches the supreme, ultimate destination (yāti parāṃ gatim).
