tad visva-nabhim tv ativartya visnor
namaskrtam brahma-vidam upaiti
kalpayuso yad vibudha ramante
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This Sisumara is the pivot for the turning of the complete universe, and it is called the navel of Visnu [Garbhodakasayi Visnu]. The yogi alone goes beyond this circle of Sisumara and attains the planet [Maharloka] where purified saints like Bhrgu enjoy a duration of life of 4,300,000,000 solar years. This planet is worshipable even for saints who are transcendentally situated.
