SB 8.17.26

namas te prsni-garbhaya
 veda-garbhaya vedhase
tri-nabhaya tri-prsthaya
 sipi-vistaya visnave
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
I offer my respectful obeisances unto You, the all-pervading Lord Visnu, who have entered the cores of the hearts of all living entities. All the three worlds reside within Your navel, yet You are above the three worlds. Formerly You appeared as the son of Prsni. To You, the supreme creator, who are understood only through Vedic knowledge, I offer my respectful obeisances.
