mostly people are engaged in the animal propensities of life. Āhāra-nidrā-bhaya-maithunaṁ ca: eating, sleeping, sex life and defense. They are busy. But these things are visible in the animal life also. Then what is the special significance of the human life? Human life means athāto brahma jijñāsā. They, the human being should be inquisitive to understand Brahman. That is the special significance of human life.
Narottama dāsa Ṭhākura therefore sings, manuṣya-janama pāiyā, rādhā-kṛṣṇa nā bhajiyā, jāniyā śuniyā biṣa khāinu (from Prārthanā). Narottama dāsa Ṭhākura laments, hari hari bifale janama goṅāinu: "My Lord, I have simply spoiled my life." Why you have spoiled? You are eating very nicely, sleeping very nicely." No.
Manuṣya-janama . . . rādhā-kṛṣṇa, manuṣya-janama. This human form of life is especially meant for understanding Rādhā-Kṛṣṇa. Kṛṣṇa means Rādhā-Kṛṣṇa. Kṛṣṇa means everything, samagram. To understand Kṛṣṇa, that is the special mission of human life. "So I did not try for it. I simply carried away by the waves of māyā."
