In that spiritual sky, on the four sides of Nārāyaṇa, are the second expansions of the quadruple expansions of Dvārakā.
Within the spiritual sky is a second manifestation of the quadruple forms of Dvārakā from the abode of Kṛṣṇa. Among these forms, which are all spiritual and immune to the material modes, Śrī Baladeva is represented as Mahā-saṅkarṣaṇa.
The activities in the spiritual sky are manifested by the internal potency in pure spiritual existence. They expand in six transcendental opulences, which are all manifestations of Mahā-saṅkarṣaṇa, who is the ultimate reservoir and objective of all living entities. Although belonging to the marginal potency, known as jīva-śakti, the spiritual sparks known as the living entities are subjected to the conditions of material energy. It is because these sparks are related with both the internal and external potencies of the Lord that they are known as belonging to the marginal potency.
