The transcendental goddess Śrīmatī Rādhārāṇī is the direct counterpart of Lord Śrī Kṛṣṇa. She is the central figure for all the goddesses of fortune. She possesses all the attractiveness to attract the all-attractive Personality of Godhead. She is the primeval internal potency of the Lord.” This text is from the Bṛhad-gautamīya-tantra.
(Sri Caitanya Caritamrta------1:4:83------translation).

Therefore Rādhā is parama-devatā, the supreme goddess, and She is worshipable for everyone. She is the protectress of all, and She is the mother of the entire universe.
(Sri Caitanya Caritamrta------1:4:89------translation).

Lord Kṛṣṇa enchants the world, but Śrī Rādhā enchants even Him. Therefore She is the supreme goddess of all.
(Sri Caitanya Caritamrta------1:4:95------translation).

According to expert opinion, Lakṣmī, the goddess of fortune, is a subordinate expansion of Śrīmatī Rādhārāṇī. As Kṛṣṇa has numerous expansions of viṣṇu-mūrtis, so His pleasure potency, Rādhārāṇī, also has innumerable expansions of goddesses of fortune. Therefore the goddess of fortune, Lakṣmījī, is always eager to be elevated to the position of the gopīs.
