The yajnic brāhmaṇa used to test how correctly they are pronouncing Vedic mantra. The test was that one animal should be put into the fire and he would again come with fresh, young body. Then it is tested that the yajña is being performed nicely. The brāhmaṇas, the yajnic brāhmaṇa, they are pronouncing the Veda mantra correctly. This is the test. But where is that brāhmaṇa in this age? Therefore no yajña is recommended. Kalau pañca vivarjayet aśvamedham, avalambhaṁ sannyāsaṁ bāla-paitṛkam, devareṇa suta-pitṛ kalau pañca vivarjayet (CC Adi 17.164). So there is no yajña in this age. There is no yajnic brāhmaṇa. This is the only yajña: chant Hare Kṛṣṇa mantra and dance in ecstasy. This is the only yajña.
