So mind has nothing to do. Mind, simply training of the mind required. And how the mind is trained up? It is by good association. Good association, our mind is trained up. Saṅgāt sañjāyate kāmaḥ. Kāma means desire. Desire is the function of the mind. And saṅgāt sañjāyate kāmaḥ. And according to the association, my mind desires like that. So we have to make good association if we want to make our mind as my friend, if I want to make my mind as my friend, then I have to associate with sādhu. Tasmāt satsu sajyeta buddhimān. Buddhimān means intelligent person. He must associate with satsu. Satsu means those who are trying for self-realization. They are called sat. Sat and asat. Asat means who are trying for the temporary things. Matter is temporary. My body is temporary. So if I simply engage myself for bodily pleasures, sense gratification, then I am engaging myself to temporary things. But if I engage myself for self-realization, the permanent thing, then I am engaging myself to the sat, or to the permanent. Tasmāt satsu sajyeta buddhimān. "Anyone who is intelligent, he should associate with persons who are trying to elevate themselves for self-realization." That is called sat-saṅga, good association.
