Once we attain the perfectional stage, we attain ecstatic love of Godhead. In that state we cannot remain without Kṛṣṇa for a moment. That is called bhāva, and that bhāva may increase to mahā-bhāva. This is not possible for ordinary human beings, but it was possible for the gopīs and Rādhārāṇī. Indeed, they could not live without Kṛṣṇa. This is the highest stage of liberation.
Teachings of Lord Kapila, Chapter 8
