sei puruṣa virajāte karena śayana ‘kāraṇābdhiśāyī’ nāma jagat-kāraṇa
“That original Personality of Godhead, named Saṅkarṣaṇa, first lies down in the river Virajā, which serves as a border between the material and the spiritual world. As Kāraṇābdhiśāyī Viṣṇu, He is the original cause of the material creation.
