अग्निमात्मन्यरण्यां वा राजदैववशाद्ध्रुवम् । अग्नित्यागभयादुक्तं समारोपितमुच्यते ६ ।
The sacrificial fire shall be maintained either in the Ātman or in the Araṇī (the sacrificial churning twig from which fire is kindled) lest the fire should be extinguished by royal or divine intercession.
संपत्करी तथा ज्ञेया सायमग्न्याहुतिर्द्विजाः । आयुष्करीति विज्ञेया प्रातः सूर्याहुतिस्तथा ७ ।
O brahmins, the offering in the fire in the evening for the fire-god is the bestower of prosperity. The offering in the morning for the sun-god is conducive to longevity.
This Agni Yajna is said to be performed during the day, as it is associated with the placement of the Sun. Offering in the fire is made to the gods, specifically Indra, who is invoked for the welfare of all the divine beings and their well-being.
देवयज्ञं हि तं विद्यात्स्थालीपाकादिकान्क्रतून् । चौलादिकं तथा ज्ञेयं लौकिकाग्नौ प्रतिष्ठितम् ९ ।
The different sacrifices Sthālīpāka etc. for the propitiation of Indra and other gods by offerings in the fire are called Devayajña. The rites of Caula (ceremony of tonsure) etc. are performed in the ordinary fire.
