Real devotee, santaḥ, saintly persons, their eyes are purified by the ointment of love of Godhead. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti (Bs. 5.38). They are seeing Kṛṣṇa or his worshipable God... Kṛṣṇa has many forms. Rāmādi-mūrtiṣu. Kṛṣṇa has His form as Lord Rāmacandra, as Varāha, as Kūrma, as Nṛsiṁha. Ananta-koṭi. Innumerable forms He has got. All of them are Kṛṣṇa. So a devotee, on account of his eyes being smeared with the ointment of love of God, he sees Kṛṣṇa twenty-four hours within his heart. That is the vision of the devotee. Atheist class will say, "Where is God?" Because he has no eyes to see the God. But a theist class or a devotee, he sees God, or Kṛṣṇa, twenty-four hours. He does not see anything else. In the Caitanya-caritāmṛta it is said, sthāvara jaṅgama dekhe nā dekhe tāra mūrti (CC Madhya 8.274). A devotee, mahā-bhāgavata, highly advanced devotee, he sees trees, but he does not see the tree.
