Translation: 
This Śiśumāra is the pivot for the turning of the complete universe, and it is called the navel of Viṣṇu [Garbhodakaśāyī Viṣṇu]. The yogī alone goes beyond this circle of Śiśumāra and attains the planet [Maharloka] where purified saints like Bhṛgu enjoy a duration of life of 4,300,000,000 solar years. This planet is worshipable even for saints who are transcendentally situated.
