Prabhupāda: People think that "These Kṛṣṇa conscious men, Hare Kṛṣṇa people, they are escaping." What is that, escaping? We are not escaping. We are practically taking the real activities. Paraṁ dṛṣṭvā nivartate (BG 2.59). Although people see that we do not work, we do not go to the factory, we do not to the mine, we do not go to the so many, so many things, or professional. We do not become lawyer, engineer. They say that we are escaping. No. You see we are always busy, twenty-four hours busy. I am old man of eighty years; still, I am busy. I am traveling all over the world, writing book at night, talking with visitors, and so many things. You can see. So where we are escaping? We are the most responsible worker. So the... What is the difference? The difference is all people are engaged for sense gratification. We are engaged for satisfying Kṛṣṇa. But activities are there.
So when you engage yourself for satisfaction of Kṛṣṇa... Yajña means satisfaction of Kṛṣṇa, or Viṣṇu. Viṣṇur ārādhyate panthā nānyat-tat-toṣa-kāraṇam. This is called yajña. Yajña means worshiping Lord Viṣṇu. Tat-toṣa-kāraṇam, acting for His satisfaction. Toṣa means satisfaction. And in another place it is also said, ataḥ pumbhir dvija-śreṣṭhā varṇāśrama-vibhāgaśaḥ, svanuṣṭhitasya puṁsasya...svanuṣṭhitasya puṁsasya. Huh?
Puṣṭa-kṛṣṇa: Svanuṣṭhitasya dharmasya.
Prabhupāda: Ah. Svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam (SB 1.2.13). Everyone has got different type of activities. Formerly it was divided into four: the brāhmaṇa activity, the kṣatriya activity, the vaiśya activity, and the śūdra activity. Now it has been developed at the present moment, so many. But if you again connect all of them, they will come to the same categories or divisions. Some intelligent class of men, they are working day and night about understanding the Absolute Truth or the truth. Just like the theosophists, the philosophers, the theologists, the scientists, so many brain workers, they are working to discover better way of life, how the human society should be more and more happy.
