Kṛṣṇa is there—they are at home, but they are thinking of Kṛṣṇa, how He's walking, how His soft foot is suffering. In this way they are always absorbed in Kṛṣṇa consciousness. They are not Vedāntist. They are not brāhmins. They are not educated. They were cowherds girls. But their love of Kṛṣṇa was so intense that Lord Caitanya recommends, "Oh, there is no better worship than . . . than it was being demonstrated by the damsels of Vṛndāvana." Ramyā kācid upāsanā vraja-vadhū-vargeṇa yā kalpitā.
Then what is the source of understanding Kṛṣṇa? Śrīmad-Bhāgavatam. Amalaṁ purāṇam. If you study Śrīmad-Bhāgavatam, then you attain all these things. Śrī-caitanya-mahaprabhor matam idam. And premā pumartho mahān. So the book, Śrīmad-Bhāgavatam; the ideal worship, the damsels of Vṛndāvana; Kṛṣṇa is the worshipable object; and the necessary of life, necessity of life, is to attain love of Godhead. This is the whole mission of Caitanya Mahāprabhu, sum and substance.
Therefore Caitanya Mahāprabhu is saying here, puruṣartha-śiromaṇi prema mahā-dhana. People are . . . have their objective of life, everyone. Dharmārtha-kāma-mokṣa (SB 4.8.41). Their objective of life is . . . of course, nowadays people are different. Formerly . . . it is Vedic version, dharma, to make them religious. Therefore every civilized nation has some sort of religion. Religious . . . because without becoming religious, there is no possibility of peace and prosperity. So this is one of the aim of human society: religious.
