तत्र तं बुद्धिसंयोगं लभते पौर्वदेहिकम्।
यतते च ततो भूयः संसिद्धौ कुरुनन्दन।।6.43।।
6.43 Thee he comes in touch with the knowledge acired in his former body and strives more than before for perfection, O Arjuna.
6.43 Tatra, there, in the family of yogis; labhate, tam buddhisamyogam, he becomes endowed with that wisdom; paurva-dehikam, acired in the previous body. And yatate, he strives; bhuyah, more intensely; tatah, than before, more intensely than that tendency acired in the previous birth; samsiddau, for, for the sake of, perfection; kuru-nandana, O scion of the Kuru dynasty. How does he become endowed with the wisdom acired in the previous body? That is being answered:
Tatra tam buddhisamyogam labhate paurvadehikam; Yatate cha tato bhooyah samsiddhau kurunandana.
