How you will understand Kṛṣṇa? Kṛṣṇa is so great. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). You cannot understand Kṛṣṇa by these blunt material senses. That is not possible. You have to purify it. You have to purify it. Tat-paratvena nirmalam (CC Madhya 19.170). Simply by Kṛṣṇa consciousness, always thinking of Kṛṣṇa, all your senses will be purified. This is the process. Sevonmukhe hi jihvādau. And you can begin service with your tongue.
Now, this is also very surprising. By utilizing our tongue, we can become perfect. This is also unknown to the modern science. By utilizing the tongue, one can become perfect. Yes. This is the process. If by the tongue you chant Hare Kṛṣṇa mantra, and by the tongue you taste prasādam, you will be perfect, simply by executing these two things. Do not accept anything, do not allow the tongue to touch anything which is not offered to Kṛṣṇa. This is one item. And another item—engage the tongue, always chanting Hare Kṛṣṇa. You become perfect. Is it very difficult task? Anyone can do. Hare Kṛṣṇa mahā-mantra, anyone can chant. And nice prasādam, anyone can take. And actually, it is happening so. How these European, American boys and girls, they are advancing, they are realizing? Simply by that process, tongue: chant Hare Kṛṣṇa, take prasādam. So you can introduce this process all over the world. Give them chance to chant Hare Kṛṣṇa mantra. But it is difficult also. There was a cartoon? That one...?
Prabhupāda: No, no, that one old lady is requesting her husband, "Chant chant chant," and the husband is replying, "Can't can't can't." (laughter). There was a cartoon. So we are requesting everyone, "Please chant," and they are replying, "Can't." Still, they will not chant. This is the difficulty. Otherwise, we can deliver all the people on this earth back to home, back to Godhead, simply by this process. Chant and take prasādam. This should be... Just like the other day we held the festival, Ratha-yātrā. Chant and take prasādam. That's all. Organize this all over the world. They will be saved. They will understand Kṛṣṇa. Sevonmukhe hi jihvādau svayam... (Brs. 1.2.234), Kṛṣṇa will appear.
