It is said: adhyāpanaṁ brahma-yajñaḥ pitṛ-yajñas tu tarpaṇamhomo daivo balir bhauto nṛ-yajño ’tithi-pūjanam “By offering oblations with ghee, one satisfies the demigods. By studying the Vedas, one performs brahma-yajña, which satisfies the great sages. Offering libations of water before one’s forefathers is called pitṛ-yajña. By offering tribute, one performs bhūta-yajña. By properly receiving guests, one performs nṛ-yajña.” These are the five yajñas that liquidate the five kinds of indebtedness — indebtedness to the demigods, great sages, forefathers, living entities and common men. Therefore one has to perform these five kinds of yajñas. But when one takes to the saṅkīrtana-yajña (the chanting of the Hare Kṛṣṇa mantra), one does not have to perform any other yajña. In Śrīmad-Bhāgavatam, Nārada Muni made a statement about the systematic performance of bhāgavata-dharma in connection with statements previously made by the nine Yogendras before Mahārāja Nimi. The sage Karabhājana Ṛṣi explained the four incarnations of the four yugas, and at the end, in this verse (text 141), he explained the position of Kṛṣṇa’s pure devotee and how he is absolved of all debts.
