Śrī Kṛṣṇa is present by His name, by His form, by His pastimes, by His paraphernalia, by His qualities. Anything about Kṛṣṇa is non-different. Kṛṣṇa and Kṛṣṇa's name, it is the same. There is no difference. In the materialistic view, there is difference between the substance and the name. Just like water. If you are thirsty, simply if I chant, "Water, water, water," it will not quench your thirst. You require the substance, water. So similarly, a, a person's photograph or a statue is different from the person. If there is a photograph of a certain gentleman and if you want to do business with the photograph, it is not possible. You'll have to seek for the actual person. But in case of Kṛṣṇa, it is not like that. Kṛṣṇa, the person, and Kṛṣṇa's name, Hare Kṛṣṇa, the same thing. It is not that we are chanting "Kṛṣṇa, Kṛṣṇa" and this Kṛṣṇa, the Supreme Personality of Godhead, is different. No. Nāma rūpe kṛṣṇa avatāra. The name of Kṛṣṇa and Kṛṣṇa, the person, identical.
Just like we are worshiping the form of Rādhā-Govinda, Rādhā-Mādhava, Rādhā-Dāmodara. So this form, atheists will say that "This is statue." But a theist person, who knows Kṛṣṇa, he will see this form of Kṛṣṇa not different from the original person, Kṛṣṇa. Just like Caitanya Mahāprabhu, when He entered the Jagannātha temple, He immediately fainted, "Here is My Lord." Others who are going in the Jagannātha temple, they are seeing something made of wood.
