3.5.40

mārganti yat te mukha-padma-nīḍaiś chandaḥ-suparṇair ṛṣayo vivikte /
yasyāgha-marṣoda-sarid-varāyāḥ padaṃ padaṃ tīrtha-padaḥ prapannāḥ //

40. We have resorted (we resort to) to those holy feet of Thine which are the source of the Ganga, the most sacred of all the rivers whose waters cleanse men of their sin, and of which (the feet) Rishis in solitude are in search with the help of the birds of Vedas which dwell in the nest of Thy Lotus-like face.
