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 plane (Maharloka) where purified saints like Bhrgu enjoy a duration of life of 4,300,000,000 solar years. This plane is worshipable even for the saints who are transcendentally situated.
