Śrīmad-Bhāgavatam · Text 4.30.45
Who is speaking and story frame
ततोऽग्निमारुतौ राजन्नमुञ्चन्मुखतो रुषा ।
महीं निर्वीरुधं कर्तुं संवर्तक इवात्यये ॥ ४५ ॥
tato ’gni-mārutau rājann
amuñcan mukhato ruṣā
mahīṁ nirvīrudhaṁ kartuṁ
saṁvartaka ivātyaye
My dear King, at the time of devastation, Lord Śiva emits fire and air from his mouth out of anger. To make the surface of the earth completely treeless, the Pracetās also emitted fire and air from their mouths.
