Abhinnatvān nāma-nāminoḥ (CC Madhya 17.133). These are the descriptions of the Vedic literature. Abhinnatvān nāma-nāminoḥ. Nāma cintāmaṇiḥ kṛṣṇaḥ. Kṛṣṇa's name is cintāmaṇi. Cintāmaṇi means spiritual. Cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa-lakṣāvṛteṣu (Bs. 5.29). These are the Vedic descriptions. Where Kṛṣṇa lives, the place is described: cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa-lakṣāvṛteṣu surabhīr abhipālayantam (Bs. 5.29). So nāma, the holy name of Kṛṣṇa, is also cintāmaṇi, spiritual. Nāma cintāmaṇiḥ kṛṣṇaḥ. He is the same Kṛṣṇa, person. Nāma cintāmaṇiḥ kṛṣṇaś caitanya (CC Madhya 17.133). Caitanya means not dead, but living entity. You can get the same benefit by chanting name as you get personally talking with Kṛṣṇa. That is also possible. But this will be gradually realized. Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ. Rasa-vigraha means the pleasure, reservoir of all pleasure. As, as you chant the name of Hare Kṛṣṇa, so gradually you relish some transcendental pleasure. Just like these boys and girls, while chanting, they're dancing in joyfulness. Nobody could follow them. But they are not crazy fellows, that they're chanting. Actually, they're getting some pleasure, transcendental pleasure. Therefore they're dancing. It is not that the dog-dance. No. It is really spiritual dance, the soul's dance. So... Therefore, He's called rasa-vigraha, reservoir of all pleasure.
Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ pūrṇaḥ (CC Madhya 17.133). Complete. Not that one percent less than Kṛṣṇa. No. Cent percent Kṛṣṇa. Complete. Pūrṇa. Pūrṇa means complete. Pūrṇaḥ śuddhaḥ. Śuddha means purified. There is contamination in the material world. Material, any name you chant, because it is materially contaminated, you cannot continue it for very long. This is another experience. But this chanting of Hare Kṛṣṇa mantra, if you go on chanting for twenty-four hours, you'll never feel fatigued. That is the test. You go on chanting. These boys can chant twenty-four hours, without eating anything, without drinking water. It is so nice. Because it is complete, spiritual, śuddha. Śuddha means pure. Not materially contaminated. Material pleasure, any pleasure... The highest pleasure in the material world is sex. But you cannot enjoy it twenty-four hours. That is not possible. You can enjoy it for few minutes. That's all. Even if you are forced to enjoy, you'll reject it: "No, no more." That is material. But spiritual means there is no end. You can enjoy perpetually, twenty-four hours. That is spiritual enjoyment. Brahma-saukhyam anantam (SB 5.5.1). Anantam. Anantam means unending.
So in order to enjoy this spiritual pleasure, you have to practice some tapasya, austerity. Because you are spiritual, every one of us, spiritual. Ahaṁ brahmāsmi. We are not this material body. We change. It is for certain years. Again we change: another body, another body. This changing of body is going on because we are seeking material pleasure. So God is giving us different types of body for enjoying different types of material pleasure. But if we want to enjoy spiritual pleasure, then you do not require to change body. That is the mission of Kṛṣṇa consciousness. That every one of you want pleasure, but that pleasure, in the material world, you cannot enjoy perpetually. But if you purify yourself of this material contamination, if you do not accept this material body again, and you remain in your spiritual body, then you enjoy transcendental bliss eternally.
