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."
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.
