tato ’param upadaya
sa sargaya mano dadhe
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereafter Brahma accepted another body, in which sex life was not forbidden, and thus he engaged himself in the matter of further creation.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In his former body, which was transcendental, affection for sex life was forbidden, and Brahma therefore had to accept another body to allow himself to be connected with sex. He thus engaged himself in the matter of creation. His former body transformed into fog, as previously described.
