Unless we control the senses, we are put into this avidyā-jāl, network of . . . And out of all the senses, Bhaktivinoda Ṭhākura says, tā'ra madhye jihvā—jihvā means tongue—jihvā ati, lobhamoy sudurmati. It is very greedy. Jihvā, to control the tongue . . . To control the senses means begin with the controlling the tongue. That is also very difficult job. So therefore to control the tongue, best thing is to take kṛṣṇa-prasādam. First of all, offer to Kṛṣṇa and then take. Tā'ra madhye jihvā ati, lobhamoy sudurmati tā'ke jetā koṭhina soṁsāre. Kṛṣṇa baḍo-doyāmoy karibāre jihvā jay. At least if we take it as a vow that "I shall not eat anything which is not offered to Kṛṣṇa," that will help us. Kṛṣṇa baḍo-doyāmoy, karibāre jihvā jay svaprasād ānna dilā bhāi.
So with the tongue begins spiritual life. If we restrict our tongue not to talk uselessly, simply talk of Kṛṣṇa or chant Hare Kṛṣṇa, read Kṛṣṇa books, chant Hare Kṛṣṇa, and when you are hungry, take kṛṣṇa-prasādam, then it will be possible, you can control the tongue. And if you can control the tongue, then you can control other senses very easily. Therefore Bhaktivinoda Ṭhākura has given a very easy formula, tā'ra madhye jihvā ati, lobhamoy sudurmati tā'ke jetā koṭhina soṁsāre, kṛṣṇa baḍo-doyāmoy, kori . . . Kṛṣṇa is so kind that from Vaikuṇṭha He has come here in this remote village of America—He's so kind—just to accept your service. Don't think that "Here is a doll." No. Kṛṣṇa. Kṛṣṇa, on the request of devotee, He has come. You should always remember this, that "Here is Kṛṣṇa, personally present." Just like Caitanya Mahāprabhu . . . It requires only advanced sense. When He saw Jagannātha at Purī temple, He immediately fainted: "Here is My Lord." So it is only advanced understanding.
