4.24.52

padā śarat-padma-palāśa-rociṣā nakha-dyubhir no 'ntar-aghaṃ vidhunvatā /
pradarśaya svīyam apāsta-sādhvasaṃ padaṃ guro mārga-gurus tamo-juṣām //

52. O father, O preceptor, with Thy feet which are beautiful like the petals of autumn lotus, which drive away the sin in our mind and heart by means of the rays shooting from the nails, may Thou reveal unto us, as our asylum, Thy form which has rescued (Prahlada and others) from fear; for Thou art the preceptor to indicate the way to us who are in darkness.
