As for the urges of the tongue, we all experience that the tongue wants to eat palatable dishes. Generally we should not allow the tongue to eat according to its choice, but should control the tongue by supplying prasāda. The devotee's attitude is that he will eat only when Kṛṣṇa gives him prasāda. That is the way to control the urge of the tongue. One should take prasāda at scheduled times and should not eat in restaurants or sweetmeat shops simply to satisfy the whims of the tongue or belly. If we stick to the principle of taking only prasāda, the urges of the belly and tongue can be controlled.
In a similar manner, the urges of the genitals, the sex impulse, can be controlled when not used unnecessarily. The genitals should be used to beget a Kṛṣṇa conscious child, otherwise they should not be used. The Kṛṣṇa consciousness movement encourages marriage not for the satisfaction of the genitals but for the begetting of Kṛṣṇa conscious children. As soon as the children are a little grown up, they are sent to our Gurukula school, where they are trained to become fully Kṛṣṇa conscious devotees. Many such Kṛṣṇa conscious children are required, and one who is capable of bringing forth Kṛṣṇa conscious offspring is allowed to utilize his genitals.
When one is fully practiced in the methods of Kṛṣṇa conscious control, he can become qualified to be a bona fide spiritual master.
In his Anuvṛtti explanation of Upadeśāmṛta, Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura writes that our material identification creates three kinds of urges—the urge to speak, the urge or demands of the mind and the demands of the body. When a living entity falls victim to these three types of urges, his life becomes inauspicious. One who practices resisting these demands or urges is called tapasvī, or one who practices austerities. By such tapasya one can overcome victimization by the material energy, the external potency of the Supreme Personality of Godhead.
When we refer to the urge to speak, we refer to useless talking, such as that of the impersonal Māyāvādī philosophers, or of persons engaged in fruitive activities (technically called karma-kāṇḍa), or of materialistic people who simply want to enjoy life without restriction. All such talks or literatures are practical exhibitions of the urge to speak. Many people are talking nonsensically and writing volumes of useless books, and all this is the result of the urge to speak. To counteract this tendency, we have to divert our talking to the subject of Kṛṣṇa. This is explained in Śrīmad-Bhāgavatam (SB 1.5.10-11):
- na yad vacaś citra-padaṁ harer yaśo
- jagat-pavitraṁ pragṛṇīta karhicit
- tad vāyasaṁ tīrtham uśanti mānasā
- na yatra haṁsā niramanty uśik-kṣayāḥ
"Those words which do not describe the glories of the Lord, who alone can sanctify the atmosphere of the whole universe, are considered by saintly persons to be like unto a place of pilgrimage for crows. Since the all-perfect persons are inhabitants of the transcendental abode, they do not derive any pleasure there."
- tad-vāg-visargo janatāgha-viplavo
- yasmin prati-ślokam abaddhavaty api
- nāmāny anantasya yaśo 'ṅkitāni yat
- śṛṇvanti gāyanti gṛṇanti sādhavaḥ
"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."
