Pradyumna: "In the Bhagavad-gītā (BG 7.3) it is said that out of many thousands of ordinary men, one fortunate man endeavors for perfection in life. Mostly they are conducted by the modes of passion and ignorance, and thus they are engaged always in lust, desire, hankerings, ignorance and sleep. Out of many such manlike animals, there is actually a man who knows the responsibility of human life and thus tries to make life..."
Prabhupāda: So human being in the modes of ignorance and passion, they are animals. They are not considered as human being. They are animals. Rajas-tamo-bhāvāḥ, kāma-lobhādayaś ca ye (SB 1.2.19). So actually a person is considered to be human being when he comes to the platform of goodness or he acquires the quality of a bona fide brāhmaṇa. Then he is considered as human being.
