The distinction between animal and man is that . . . man and animal, they have got common platform of these four principles of life: eating, sleeping, mating and defending. The only extra qualification of man is that he can come to understand what is Kṛṣṇa and what is God. That is his special qualification. But because they are trying to keep themselves within the limit of sense gratification, they're coming again and again to that same platform, eating, sleeping, mating and defending, without Kṛṣṇa consciousness.
So this is the secret how to become Kṛṣṇa conscious. We should not limit ourself under certain area. And how it is possible? That is Kṛṣṇa consciousness, that "I am eternal servant of Kṛṣṇa, or God." That is Kṛṣṇa consciousness. So if we keep ourself within some limit, then it will be not possible to understand what is Kṛṣṇa consciousness. Matir na kṛṣṇe parataḥ svato vā mitho 'bhipadyeta gṛha . . . these are verses . . . Bhāgavata verses can be explained for so many days. They are so important. Yes.
The another verse is that why they are keeping themself within the limit of this sense gratificatory platform. That is answered in Bhāgavata:
- na te viduḥ svārtha-gatiṁ hi viṣṇuṁ
- durāśayā ye bahir-artha-māninaḥ
- (SB 7.5.31)
This is very important. These foolish persons, they do not know what is the ultimate goal of their life. Na te viduḥ svārtha-gatiṁ hi viṣṇum. They do not know that their self-interest . . . everyone is self-interest. Everyone is eager to look after his self-interest, but they do not know what is the self-interest. Durāśayā.
Because they do not know, therefore, out of ulterior motive, they are thinking that, "Satisfaction in the material way of life will give me ultimate pleasure or ultimate satisfaction. That is my ultimate goal." Therefore the scientist, the politician, everyone is trying, making their own plan. And what is that plan? By manipulating this external energy, dura . . . bahir-artha, bahir-artha-māninaḥ.
