Pradyumna: "By rendering devotional service unto the Personality of Godhead, Śrī Kṛṣṇa, one immediately acquires causeless knowledge and detachment from the world." (SB 1.2.7)
Prabhupāda: So in the previous verse it has been discussed, what is first-class religion. Sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6). In the lower animal life, lower species of life, there is no question of religion. We have discussed many times that there is a gradual process of evolution from low..., lower animal life to the human life. Aśītiṁ caturaś caiva. Aśīti means eighty, catura means four, lakṣām, eighty-four lakhs, 8,400,000. Non... To tell...(?) Janma paryayāt. This is the evolution. From lower animals, from fish to plants, trees, insects, reptiles, birds, beasts. In this way, we come to the human form of life, and this human form of life is meant for dharma. Practically also, we see that the state laws, state laws are meant for the human beings. State laws are not for the animals. Animals, they do not require to observe the state laws. Neither they are able to do so. That is the difference between animal and human being.
