So we are so-called materially suffering and enjoying according to this body. Therefore this body, this human form of body, is a great opportunity, because God realization begins by engaging the tongue. Sevonmukhe hi jihvādau (Brs. 1.2.234). By engaging the tongue in the loving service of the Lord, one can make advance in Kṛṣṇa consciousness, ultimate realization of God, the tongue. So this tongue in the human body can be engaged. In other body, in the cat's body, dog's body, tiger's body . . . tiger may be a very powerful animal. No animal is powerful or better than human beings. That is accepted.
So this human form of life is a great boon to the living entity who is traveling through the cycle of birth and death, perpetually changing different sorts of body. Here is the opportunity, human form of body. We can utilize the tongue properly and get out of these clutches. Sevonmukhe hi jihvādau. So sevā, sevā means service—jihvā ādau, beginning from the tongue.
So if we can keep our tongue engaged, always chanting Hare Kṛṣṇa mantra . . . because "Kṛṣṇa," this sound, is not different from Kṛṣṇa. Kṛṣṇa is absolute. Nothing is different from Him. Kṛṣṇa and Kṛṣṇa's name is not different. In the material sense, everything is different. I myself is different from this body. I am not this body. But Kṛṣṇa is not like that. Kṛṣṇa and Kṛṣṇa's body is the same.
Avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritāḥ (BG 9.11). Kṛṣṇa says in the Bhagavad-gītā, "Rascals and fools, they deride at Me because I appear as a human being. They are thinking just like I am ordinary human being." Paraṁ bhāvam ajananto. "These rascals do not know what is My influence and what I am." Paraṁ bhāvam. "What is My nature they do not know. Without knowing Me, they consider, 'Kṛṣṇa is an ordinary human being.' " Avajānanti mūḍha. This very particular word has been used, mūḍha. Mūḍha means rascals.
So in spite of this warning, there are so many rascals passing as big scholars. They say like this. When there is order of Kṛṣṇa that, "You surrender unto Me," the rascals comment, "It is not to Kṛṣṇa but the unborn spirit which is within Kṛṣṇa." He does not know that Kṛṣṇa is not different from His body, Kṛṣṇa is not different from His name, Kṛṣṇa is not different from His fame. Anything pertaining to Kṛṣṇa is Kṛṣṇa. They are monists, they are philosophizing that oneness, but as soon as they come to Kṛṣṇa, immediately they divide: "Kṛṣṇa is different from His body," or "Kṛṣṇa's body is different from Kṛṣṇa."
So ataḥ śrī-kṛṣṇa-nāmādi. So Kṛṣṇa's name and Kṛṣṇa is not different. Therefore, as soon as my tongue touches the holy name of Kṛṣṇa, that means immediately it associates with Kṛṣṇa. So if you constantly keep yourself associated with Kṛṣṇa by chanting this mantra, Hare Kṛṣṇa, then just imagine how you are being easily purified simply by this process, chanting, jihvādau, engaging the tongue in chanting.
And your tongue wants very palatable dishes to taste. So Kṛṣṇa is very kind. He has given you hundreds and thousands of palatable dishes, remnants of foodstuff eaten by Him. You eat. In this way, if you simply make it a determination that, "I shall not allow my tongue to taste anything which is not offered to Kṛṣṇa, and I shall engage my tongue always chanting Hare Kṛṣṇa," then all perfection is within your hold. All perfection. Two simple things.
Don't eat anything which is not offered to Kṛṣṇa. That's all. Our Kṛṣṇa prasādam are so variegated, nice varieties . . . the variety is the mother of enjoyment. How much enjoyment you want with your tongue? You can have simply by eating Kṛṣṇa prasādam. And the more your tongue is purified, the more you relish the chanting of Hare Kṛṣṇa mantra. Relish. Ānandāmbudhi-vardhanam.
It is stated by Lord Caitanya Mahāprabhu that it increases the ocean of bliss, transcendental bliss. Ocean does not increase. We have no experience within this material world. If ocean would have increased, then all the lands would have been swallowed up many long, long years ago. Ocean does not increase. But this ocean, transcendental bliss, is increasing. Some of you must have experienced, those who are actually relishing.
The authorities like Rūpa Gosvāmī, he says that, "What I shall chant with one tongue? If I would have millions of tongues, then I could chant a little more. And what I shall hear with two ears?" So he's expecting, he's aspiring to have millions of ears and trillions of tongue to relish this chanting Hare Kṛṣṇa. So that is another stage, of course, when this chanting will be so melodious that we shall try to have more ears and more tongue to utilize it.
Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). By our present senses, we cannot understand what is Kṛṣṇa, or what is God, what is His name, what is His form, what is His quality. Therefore immediately if we try to understand Kṛṣṇa by His picture, "Oh, Kṛṣṇa is embracing Rādhārāṇī or the gopīs," we shall mistake. Because unless our senses are purified, we shall accept Kṛṣṇa and Rādhārāṇī as ordinary young boy or girl and their dealings. But actually it is not. It is pure.
Caitanya-caritāmṛta-kar has distinguished that the loving affairs of the gopīs with Kṛṣṇa and ordinary, these lustful dealings of human beings, there is a gulf of difference. He compared that the gopīs' love with Kṛṣṇa is gold, and our so-called love here is iron. As there is difference between gold and iron, similarly there is difference between the loving affairs of gopīs with Kṛṣṇa and these mundane, so-called lusty affairs between man and women or boys and girls. It is never equal.
Therefore, ataḥ śrī-kṛṣṇa-nāmādi na bhaved (Brs. 1.2.234). These present senses, these impure senses, contaminated senses, cannot understand Kṛṣṇa; therefore we should follow this principle: sevonmukhe hi jihvādau. First of all, engage chanting Hare Kṛṣṇa. There is Rādhā and Kṛṣṇa. Hara is Rādhā, and Kṛṣṇa there is. But don't try to understand by the present senses, but simply chant Their holy name, Hare Kṛṣṇa. Then ceto-darpaṇa-mārjanam (CC Antya 20.12). When your the dust on the mirror of your heart will be cleansed, and it will cleanse by simply chanting, ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpaṇam, and there will be no more any material condition . . .
