"The Lord is beyond the inferior and marginal energies as above mentioned, and His spiritual energy is manifested in three different phases: as eternal existence, eternal bliss and eternal knowledge. As far as eternal existence is concerned, it is conducted by the sandhinī potency; similarly, bliss and knowledge are conducted by the hlādinī and saṁvit potencies respectively. As the supreme energetic Lord, He is the supreme controller of the spiritual, marginal and material energies. And all these different types of energies are connected with the Lord in eternal devotional service.
