BG 6.43

On taking such a birth, he revives the divine consciousness of his previous life, and he again tries to make further progress in order to achieve complete success, O son of Kuru.

6.43. There in that life, he gains (regains) that link of mentality transmitted from his former body. Conseently once again he strives for a full success, O rejoicer of the Kurus !

6.43 Then the experience acquired in his former life will revive, and with its help he will strive for perfection more eagerly than before.

6.43 See Comment under 6.45

6.43 - 6.44 There, in that existence, he regains the mental disposition for Yoga that he had in the previous birth. Like one awakened from sleep, he strives again from where he had left before attaining complete success. He strives so as not to be defeated by impediments. This person who has fallen away from Yoga is borne on towards Yoga alone by his previous practice, i.e., by the older practice with regard to Yoga. This power of Yoga is well known. Even a person, who has not engaged in Yoga but has only been desirous of knowing Yoga, i.e., has failed to follow it up, acries once again the same desire to practise Yoga. He then practises Yoga, of which the first stage is Karma Yoga, and transcends Sabda-brahman (or Brahman which is denotable by words). The Sabda-brahman is the Brahman capable of manifesting as gods, men, earth, sky, heaven etc., namely, Prakrti. The meaning is that having been liberated from the bonds of Prakrti, he attains the self which is incapable of being named by such words as gods, men etc., and which comprises solely of knowledge and beatitude. After thus describing the glory of Yoga the verse says:

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:

6.43 There he regains the disposition of mind which he had in his former body, O Arjuna, and from there he strives much more for success inYoga.

6.43 There he becomes endowed with that wisdom acired in the previous body. and he strives more than before for perfection, O scion of the Kuru dynasty.
