Very simple process of awakening Kṛṣṇa consciousness. This ātma-ruciḥ . . . ātma-ruciḥ means attraction for the self, or soul. There are ātmā. Ātmā means sometimes this body. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). Gross materialists, they think that, "I am this body." That is also ātma-ruciḥ. They are busy to maintain this body, to decorate this body, to feed this body, to satisfy the senses of the body. This is also ātma-ruciḥ, because the body is also called ātmā. So this is another ātma-ruciḥ, materialist. Then ātmā means mind also, mental speculation, very much busy in mental speculation. That is also ātma-ruciḥ. And the . . . the topmost ātma-ruciḥ, topmost means that is real ātma-ruciḥ, to be attracted by the self or Superself. That is ātma-ruciḥ.
So our business is to awaken that Supreme ātma-ruciḥ. That is Kṛṣṇa consciousness. Supreme ātma-ruciḥ, supreme ātmā. Kṛṣṇa says, mattaḥ parataraṁ nānyat (BG 7.7). You can take in different platform different kinds of attraction, but when our attraction is in Kṛṣṇa, that is supreme. So just like for bodily comforts, there are so many scientists, physiologists, biologists, they are trying to understand the constitution of the body. They are busy. And similarly, mental speculators, philosophers, they are also busy. Similarly, the ultimate ātma-ruciḥ if we want to know, then we should be busy with such persons who are engaged in that type of ātma-ruciḥ. That is called sādhu-saṅga (CC Madhya 22.83). Saṅgāt sañjāyate kāmaḥ. As you associate, so your desires become, I mean to say, attached.
So here it is said that dvijaiḥ . . . ucchiṣṭa-lepān anumodito dvijaiḥ. Dvijaiḥ, the brāhmaṇa. And the supreme brāhmaṇa is the devotee, kṛṣṇaika-śaraṇa. So Nārada Muni, in his previous birth, he was engaged in washing the dishes, eating the foodstuffs left by the dvijaiḥ, by the brāhmaṇas. In this way he infected their disease. As in ordinary material sense if you eat the remnants of foodstuff of a diseased fellow, then you infect that disease. Therefore sometimes when there is a patient suffering from tuberculosis, it is strictly separated from the family to another room or another house so that . . . it is very infectious. Cholera is very infectious. Smallpox is very much infectious. There are many infectious disease. So as you infect this material disease by eating the foodstuff left by a diseased fellow, similarly, if you eat the remnants of foodstuff left by a Vaiṣṇava you become Vaiṣṇava. This is infection. So we should voluntarily accept this infection. The other infection we should avoid, but this infection we shall welcome. But the process is the same. Paraṁ dṛṣṭvā nivartate (BG 2.59). You can refrain from the lower class of infection simply by infecting yourself with the higher class, or transcendental class, of infection.
