Śrīmad-Bhāgavatam · Text 2.1.31
Who is speaking and story frame
छन्दांस्यनन्तस्य शिरो गृणन्ति
दंष्ट्रा यम: स्नेहकला द्विजानि ।
हासो जनोन्मादकरी च माया
दुरन्तसर्गो यदपाङ्गमोक्ष: ॥ ३१ ॥
chandāṁsy anantasya śiro gṛṇanti
daṁṣṭrā yamaḥ sneha-kalā dvijāni
hāso janonmāda-karī ca māyā
duranta-sargo yad-apāṅga-mokṣaḥ
They say that the Vedic hymns are the cerebral passage of the Lord, and His jaws of teeth are Yama, god of death, who punishes the sinners. The art of affection is His set of teeth, and the most alluring illusory material energy is His smile. This great ocean of material creation is but the casting of His glance over us.
