Kṛṣṇa has got so many expansions. Rāmādi-mūrtiṣu kalā-niyamena tiṣṭhan: Rāma, Nṛsiṁha, Varāha, Kūrma, Vāmana, so many, hundreds of thousands. But Kṛṣṇa is the. . .
- rāmādi-mūrtiṣu kalā-niyamena tiṣṭhan
- nānāvatāram akarod bhuvaneṣu kintu
- kṛṣṇaḥ svayaṁ samabhavat paramaḥ pumān yo
- (Bs. 5.39)
So original person, the Supreme Lord—kṛṣṇas tu bhagavān svayam (SB 1.3.28)—He also comes. Rāmādi-mūrtiṣu, Rāma, Nṛsiṁha, Varāha, that is Kṛṣṇa's expansion, incarnation, They also come, and Kṛṣṇa also come. Kṛṣṇaḥ svayaṁ samabhavat paramaḥ pumān yo. He is the Supreme Person, pumān. Pumān means the puruṣa, the enjoyer, the proprietor. That is Kṛṣṇa. So immediately you can be in touch with Kṛṣṇa by vibrating this sound, Hare Kṛṣṇa. It is so potent. Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ (CC Madhya 17.133). The name of Kṛṣṇa is cintāmaṇi, transcendental. It is not this material sound, material name. Nāma cintāmaṇiḥ kṛṣṇaś caitanya. Living force, caitan. It is not dead sound. If you want water, if you chant only "water, water, water, water," you will not get water, because it is material sound. The water substance is different from the word water. Therefore, simply by chanting "water, water," you cannot quench your thirst. You must have the substance water. That is material sound. Anything you take, simply by chanting the name, you will not get the thing. That is material.
But in the spiritual world, the name and the person or the substance is the same. There is no difference. Kṛṣṇa and Kṛṣṇa's name is the same. There is no difference. Therefore, those who are chanting "Kṛṣṇa, Kṛṣṇa, Kṛṣṇa," they are becoming more and more engladdened, enthusiastic to chant. Ānandāmbudhi-vardhanam. Caitanya Mahāprabhu says, "By chanting Hare Kṛṣṇa, the first installment of benefit is ceto-darpaṇa-mārjanam (CC Antya 20.12): you become cleansed of your heart, cleansed of the contamination of your heart." There are many verses.
