A sober person who can tolerate the urge to speak, the mind’s demands, the actions of anger and the urges of the tongue, belly and genitals is qualified to make disciples all over the world.
First one must control his speaking power. Every one of us has the power of speech; as soon as we get an opportunity we begin to speak. If we do not speak about Kṛṣṇa consciousness, we speak about all sorts of nonsense. A toad in a field speaks by croaking, and similarly everyone who has a tongue wants to speak, even if all he has to say is nonsense. The croaking of the toad, however, simply invites the snake: “Please come here and eat me.” Nevertheless, although it is inviting death, the toad goes on croaking. The talking of materialistic men and impersonalist Māyāvādī philosophers may be compared to the croaking of frogs. They are always speaking nonsense and thus inviting death to catch them. Controlling speech, however, does not mean self-imposed silence (the external process of mauna), as Māyāvādī philosophers think. Silence may appear helpful for some time, but ultimately it proves a failure. The meaning of controlled speech conveyed by Śrīla Rūpa Gosvāmī advocates the positive process of kṛṣṇa-kathā, engaging the speaking process in glorifying the Supreme Lord Śrī Kṛṣṇa. The tongue can thus glorify the name, form, qualities and pastimes of the Lord. The preacher of kṛṣṇa-kathā is always beyond the clutches of death. This is the significance of controlling the urge to speak.
