Bhagavatapurana 4.1.21

4.1.21

tapyamānaṃ tri-bhuvanaṃ prāṇāyāmaidhasāgninā /
nirgatena muner mūrdhnaḥ samīkṣya prabhavas trayaḥ //

21—22. On seeing the three worlds burn with the fire issuing from the head of the sage, and produced by the fuel of his Prānāyāmas (the control of breath and meditation) the three Lords of the world (Brahma, Vishnu and Siva) came to his hermitage—the Lords whose glories were widely sung by Apsaras women, sages, Gandharvas, Siddhās, Vidyādharas and Nagas.
