CC Adi 2.89, Purport:
According to Śrīla Jīva Gosvāmī, śambhos tu tamo-’dhiṣṭhānatvāt kajjalamaya-sūkṣma-dīpa-śikhā-sthānīyasya na tathā sāmyam: "The śambhu-tattva, or the principle of Lord Śiva, is like a lamp covered with carbon because of his being in charge of the mode of ignorance. The illumination from such a lamp is very minute. Therefore the power of Lord Śiva cannot compare to that of the Viṣṇu principle."
