Blended reading (Sanskrit + English inline)
bhagavān eka āsedam agra ātmātmanāṁ vibhuḥ ātmecchānugatāv ātmā anānā-maty-upalakṣaṇaḥ
“ ‘Before the cosmic manifestation was created, the creative propensity was merged in the Supreme Lord’s person. At that time all potencies and manifestations were preserved in His personality. The Lord is the cause of all causes, and He is the all- pervading, self-sufficient person. Before the creation, He existed with His spiritual potency in the spiritual world, wherein various Vaikuṇṭha planets are manifested.’
