Śrīmad-Bhāgavatam · Text 4.1.21
Who is speaking and story frame
तप्यमानं त्रिभुवनं प्राणायामैधसाग्निना ।
निर्गतेन मुनेर्मूर्ध्न: समीक्ष्य प्रभवस्त्रय: ॥ २१ ॥
tapyamānaṁ tri-bhuvanaṁ
prāṇāyāmaidhasāgninā
nirgatena muner mūrdhnaḥ
samīkṣya prabhavas trayaḥ
While Atri Muni was engaged in these severe austerities, a blazing fire came out of his head by virtue of his breathing exercise, and that fire was seen by the three principal deities of the three worlds.
