sansiddhaḥ

न हि ज्ञानेन सदृशं पवित्रमिह विद्यते

sansiddhaḥ — he who has attained perfection

Nothing in this world purifies like knowledge. One perfected in practice finds it in time, within.

तत्र तं बुद्धिसंयोगं लभते पौर्वदेहिकम्

sansiddhau — for perfection

There the understanding gained in the former body returns, and from there one strives again for perfection, son of Kuru.

प्रयत्नाद्यतमानस्तु योगी संशुद्धकिल्बिषः

sanśhuddha — purified

Striving with effort, purified of fault, perfected across many births, the practitioner then reaches the highest goal.
