When the old grain has been consumed the (Agrayana) Ishti with new grain, at the end of the (three) seasons the (Katurmasya-) sacrifices, at the solstices an animal (sacrifice), at the end of the year Soma-offerings.
नानिष्ट्वा नवसस्येष्ट्या पशुना चाग्निमान् द्विजः । नवान्नमद्यात्मांसं वा दीर्घमायुर्जिजीविषुः ॥ २७ ॥
A Brahmana, who keeps sacred fires, shall, if he desires to live long, not eat new grain or meat, without having offered the (Agrayana) Ishti with new grain and an animal-(sacrifice).
नवेनानर्चिता ह्यस्य पशुहव्येन चाग्नयः । प्राणानेवात्तुमिच्छन्ति नवान्नामिषगर्धिनः ॥ २८ ॥
For his fires, not being worshipped by offerings of new grain and of an animal, seek to devour his vital spirits, (because they are) greedy for new grain and flesh.
Let him not honour, even by a greeting, heretics, men who follow forbidden occupations, men who live like cats, rogues, logicians, (arguing against the Veda,) and those who live like herons.
