Srimad-Bhagavatam: Canto 2 - Chapter 1 - Verse 25
Sanskrit:
तद् विश्वनाभिं त्वतिवर्त्य विष्णो-रणीयसा विरजेनात्मनैक: ।नमस्कृतं ब्रह्मविदामुपैतिकल्पायुषो यद् विबुधा रमन्ते ॥ २५ ॥
ITRANS:
tad viśva-nābhiṁ tv ativartya viṣṇoraṇīyasā virajenātmanaikaḥnamaskṛtaṁ brahma-vidām upaitikalpāyuṣo yad vibudhā ramante
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.
