If a person is a brahmin, then his natural qualification will be like this. What is that? Satyam: he is truthful. In any circumstances he will be truthful. Even to an enemy he will disclose the secret, "This is the fact." That is truthfulness, not that I am very truthful, but when my interest is jeopardized, I tell lie. That is not truthfulness. Truthfulness means at any circumstances one will speak the plain truth. That is truthfulness. Satya śama.
Satya śaucam. Śaucam, cleanliness. There are two kinds of cleanliness: external and internal. External cleanliness by taking bath with soap and other cleansing material . . . of course, in India, the brahmins, they take . . . they cleanse themselves externally at least three times a day: in the morning, early in the morning; at noon before taking lunch; and in the evening before going to the temple. Tri-sandhyā. There are so many rules and regulation for becoming cleansed. This is external cleanliness. And there is internal cleanliness. The internal cleanliness is this chanting Hare Kṛṣṇa, ceto-darpaṇa-mārjanaṁ (CC Antya 20.12, Śikṣāṣṭaka 1), cleansing the heart. So satya śaucam and śama, equilibrium of the mind, not to become disturbed in any circumstances. That is called śama.
Dama. Dama means controlling the senses. Every one of us, we are all controlled by the senses. But one has to become the controller of the senses. That is brahmin. That is svāmī. Svāmī or gosvāmī means who is controller of the senses. My tongue wants to eat something, and if I say: "No, you cannot eat this," then . . . my eyes see something. I say: "No, you cannot see this." My hand wants to touch something.
I say: "No, you cannot do this." My legs want to go somewhere. I say: "No, you cannot do this." When one is in full control of the senses, he is called svāmī. Svāmī is not a title, it is a qualification. It is a qualification, and it is attained by a brahmin, one who is already advanced in brahminical qualification by cleansing.
Then . . . and truthfulness. Then this qualification also is there, controller. And when one is completely controller of the senses, or when one is actually svāmī or gosvāmī . . . there is no difference between these two words. Svāmī, svāmī means controller, and gosvāmī is still clearer. Go means senses, controller of the senses.
So Rūpa Gosvāmī says who can be a spiritual master. So he has given specifically this definition, that one who has got controls over the tongue, over the speech, over the mind, over the belly, and over the genital and over the anger. If anyone has control over these six things, then he can become spiritual master. Pṛthiviṁ sa śiṣyāt (Upadeśāmṛta 1), "He is allowed to make disciples all over the world." Otherwise not. These are the qualification of brahmin. Satyam śaucam śama dama titikṣā (BG 18.42). Titikṣā means tolerance.
