agnihotram ca darsas ca
paurnamasas ca purva-vat
caturmasyani ca muner
amnatani ca naigamaih
The vanaprastha should perform the agnihotra, darsa and paurnamasa sacrifices, as he did while in the grhastha-asrama. He should also perform the vows and sacrifices of caturmasya, since all of these rituals are enjoined for the vanaprastha-asrama by expert knowers of the Vedas.
Srila Bhaktisiddhanta Sarasvati Thakura has given a detailed explanation of the four rituals mentioned here, namely agnihotra, darsa, paurnamasa and caturmasya. The conclusion is that everyone should simply chant Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare and avoid the difficult entanglement of Vedic ritualistic ceremonies. If one neither chants Hare Krsna nor performs such rituals, one certainly becomes a pasandi, an atheistic fool.
