It is said in Vaikhānasa Smārtaṣūtra (Vaikhanasa Smartasutru) edited by W. Caland, which is a part of the Vaikhānasa Gṛhyaṣutra (Vaikhanasa Grijhyasutra), that it is necessary that a separate agnikuṇḍa (agnikunda) or a pot-like altar or furnace be constructed in order to offer oblations to the sacrificial fire that is lit inside the room designated for Agni by a housholder. It is this furnace that is used by the householder for his daily needs. The fire that burns inside this furnace was known as aupāsana (aupasan) Agni, i.e. fire meant for the purpose of daily worship. At a later period, however, the place reserved for Agni at any sacrificial rite, or the place where oblations were offered to the fire, came to be known as agnikuṇḍa. The raised altar for Agni from which Draupadī (Draupadi) and Dhṛṣtadyumna (Dhrishtadyumna) emerged in Mahābhārata (Mahabharata) is called agnikuṇḍadivyaṃ havyavarairyuktam agnikuṇḍāt samutthitaḥ

After the yajña (yajna) performed by Dakṣa (Daksha) ended in disaster, upon Vīrabhadra’s (Virbhadra) suggestion Dakṣa appeased Śiva (Shiva), and Śiva then emerged from Dakṣa’s agnikuṇḍa

From Brahmā’s (Brahma) agnikuṇḍa appeared the beautiful, young apsarā (apsara) called Prabhāvatī (Prabhavati).
