somas tu retaḥ savanāny avasthitiḥsaṁsthā-vibhedās tava deva dhātavaḥsatrāṇi sarvāṇi śarīra-sandhistvaṁ sarva-yajña-kratur iṣṭi-bandhanaḥ

Translation:

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 agniṣṭoma 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:

There are seven kinds of routine yajñas performed by all followers of the Vedic rituals, and they are called agniṣṭoma, atyagniṣṭoma, uktha, ṣoḍaśī, vājapeya, atirātra and āptoryāma. 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.
