On the other hand, that literature which is full of descriptions of the transcendental glories of the name, fame, forms, pastimes, etc., of the unlimited Supreme Lord is a different creation, full of transcendental words directed toward bringing about a revolution in the impious lives of this world's misdirected civilization. Such transcendental literatures, even though imperfectly composed, are heard, sung and accepted by purified men who are thoroughly honest."
The conclusion is that only when we talk about devotional service to the Supreme Personality of Godhead can we refrain from useless nonsensical talk. We should always endeavor to use our speaking power solely for the purpose of realizing Kṛṣṇa consciousness.
As for the agitations of the flickering mind, they are divided into two divisions. The first is called avirodha-prīti, or unrestricted attachment, and the other is called virodha-yukta-krodha, anger arising from frustration. Adherence to the philosophy of the Māyāvādīs, belief in the fruitive results of the karma-vādīs, and belief in plans based on materialistic desires are called avirodha-prīti. Jñānīs, karmīs and materialistic planmakers generally attract the attention of conditioned souls, but when the materialists cannot fulfill their plans and when their devices are frustrated, they become angry. Frustration of material desires produces anger.
Similarly, the demands of the body can be divided into three categories—the demands of the tongue, the belly and the genitals. One may observe that these three senses are physically situated in a straight line, as far as the body is concerned, and that the bodily demands begin with the tongue. If one can restrain the demands of the tongue by limiting its activities to the eating of prasāda, the urges of the belly and the genitals can automatically be controlled. In this connection Śrīla Bhaktivinoda Ṭhākura says:
- śarīra avidyā jāla, jaḍendriya tāhe kāla,
- jīve phele viṣaya-sāgare
- tā'ra madhye jihvā ati, lobhamāyā sudurmati,
- tā'ke jetā kaṭhina saṁsāre
- kṛṣṇa baḍa dayāmaya, karibāre jihvā jaya,
- sva-prasāda-anna dila bhāi
- sei annāmṛta khāo, rādhā-kṛṣṇa-guṇa gāo,
- preme ḍāka caitanya-nitāi
"O Lord! This material body is a lump of ignorance, and the senses are a network of paths leading to death. Somehow or other we have fallen into the ocean of material sense enjoyment, and of all the senses the tongue is the most voracious and uncontrollable. It is very difficult to conquer the tongue in this world, but You, dear Kṛṣṇa, are very kind to us. You have sent this nice prasāda to help us conquer the tongue; therefore let us take this prasāda to our full satisfaction and glorify Your Lordships Śrī Śrī Rādhā and Kṛṣṇa and in love call for the help of Lord Caitanya and Prabhu Nityānanda." There are six kinds of rasas (tastes), and if one is agitated by any one of them, he becomes controlled by the urges of the tongue. Some persons are attracted to the eating of meat, fish, crabs, eggs and other things produced by semina and blood and eaten in the form of dead bodies. Others are attracted by eating vegetables, creepers, spinach or milk products, but all for the satisfaction of the tongue's demands. Such eating for sense gratification—including the use of extra quantities of spices like chili and tamarind—is to be given up by Kṛṣṇa conscious persons. The use of pan, haritakī, betel nuts, various spices used in pan-making, tobacco, LSD, marijuana, opium, liquor, coffee and tea is indulged in to fulfill illicit demands. If we can practice accepting only remnants of food offered to Kṛṣṇa, it is possible to get free from māyā's victimization. Vegetables, grains, fruits, milk products and water are proper foods to offer to the Lord, as Lord Kṛṣṇa Himself prescribes. However, if one accepts prasāda only because of its palatable taste and thus eats too much, he also falls prey to trying to satisfy the demands of the tongue. Śrī Caitanya Mahāprabhu taught us to avoid very palatable dishes even while eating prasāda. If we offer palatable dishes to the Deity with the intention of eating such nice food, we are involved in trying to satisfy the demands of the tongue. If we accept the invitation of a rich man with the idea of receiving palatable food, we are also trying to satisfy the demands of the tongue.
