6.8.13

jaleṣu māṃ rakṣatu matsyamūrtir yādogaṇebhyo varuṇasya pāśāt /
sthaleṣu māyāvaṭuvāmano 'vyāt trivikramaḥ khe 'vatu viśvarūpaḥ //

13. May He in the form of the glorious fish protect me in waters from aquatic monsters and from the cords of Varuna; may He who of His own will appared as a brahmacharin Vamana guard me in the regions of land; may Trivikrama of all-pervading form guard me in the sky!
