11.8.3.7

sa prāṇamevāgnerādatta tasmādeṣa nānupadhmāto nānupajvalito jvalatyātto hyasya prāṇa ā ha vai dviṣato bhrātṛvyasya prāṇaṃ datte ya evaṃ veda

He (the sun) took unto himself Agni's breath; whence that (fire) does not blaze unless fanned or kindled, for its breath has been taken from it; and, verily, he who knows this takes away the breath of life from his spiteful enemy.
