Hladini, Sandhini And Samvit.
The Supreme Personality of Godhead has three kinds of internal potency, namely the hlādinī-śakti, or pleasure potency, the sandhinī-śakti, or existential potency, and the samvit-śakti, or cognitive potency. In the Viṣṇu Purāṇa (1.12.69) the Lord is addressed as follows: “O Lord, You are the support of everything. The three attributes hlādinī, sandhinīand samvit exist in You as one spiritual energy. But the material modes, which cause happiness, misery and mixtures of the two, do not exist in You, for You have no material qualities.”
(Sri Caitanya Caritamrta—-1:4:60—-purport).
