ऋषय ऊचुः । अग्नियज्ञं देवयज्क्तं ब्रह्मयज्क्तं तथैव च । गुरुपूजां ब्रह्मतृप्तिं क्रमेण ब्रूहि नः प्रभो १ ।
The sages said: O lord, please tell us in order in detail all these rites viz. the fire sacrifice, the sacrifice to gods, Brahmayajña, the worship of the preceptor and the gratification of brahmins.
सूत उवाच । अग्नौ जुहोति यद्द्रव्यमग्नियज्ञः स उच्यते । ब्रह्मचर्याश्रमस्थानां समिदाधानमेव हि २ ।
Suta said: That which is offered in the fire is called the Agni Yajna (fire sacrifice). The act of offering the sacrificial wood (Samidha) is specifically meant for those in the Brahmacharya Ashrama (student stage).
समिदग्रौ व्रताद्यं च विशेषयजनादिकम् । प्रथमाश्रमिणामेवं यावदौपासनं द्विजाः ३ ।
The offering of sacrificial wood (Samidha) and the performance of vows and special sacrifices are the practices of those in the first Ashrama. This is how the Brahmanas (dvijas) perform their worship and rituals during this stage.
आत्मन्यारोपिताग्नीनां वनिनां यतिनां द्विजाः । हितं च मितमेध्यान्नं स्वकाले भोजनं हुतिः ४ ।
O brahmins, in the case of ascetics and forest-dwellers who have consigned the sacred fire to the Ātman, taking a restricted quantity of wholesome food is itself the sacrificial offering.
