SB 3.13.38
somas tu retah savanany avasthitih
samstha-vibhedas tava deva dhatavah
satrani sarvani sarira-sandhis
tvam sarva-yajña-kratur isti-bandhanah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O Lord, Your semen is the sacrifice called soma-yajña. Your growth is the ritualistic performances of the morning. Your skin and touch sensations are the seven elements of the agnistoma sacrifice. Your bodily joints are symbols of various other sacrifices performed in twelve days. Therefore You are the object of all sacrifices called soma and asoma, and You are bound by yajñas only.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
There are seven kinds of routine yajñas performed by all followers of the Vedic rituals, and they are called agnistoma, atyagnistoma, uktha, sodasi, vajapeya, atiratra and aptoryama. Anyone performing such yajñas regularly is supposed to be situated with the Lord. But anyone who is in contact with the Supreme Lord by discharging devotional service is understood to have performed all different varieties of yajñas.
