SB 5.5.15 — If one is serious about going back home, back to Godhead, he must consider the mercy of the Supreme Personality of Godhead the summum bonum and chief aim of life. If he is a father instructing his sons, a spiritual master instructing his disciples, or a king instructing his citizens, he must instruct them as I have advised. Without being angry, he should continue giving instructions, even if his disciple, son or citizen is sometimes unable to follow his order. Ignorant people who engage in pious and impious activities should be engaged in devotional service by all means. They should always avoid fruitive activity. If one puts into the bondage of karmic activity his disciple, son or citizen who is bereft of transcendental vision, how will one profit? It is like leading a blind man to a dark well and causing him to fall in.

SB 5.5.16 — Due to ignorance, the materialistic person does not know anything about his real self-interest, the auspicious path in life. He is simply bound to material enjoyment by lusty desires, and all his plans are made for this purpose. For temporary sense gratification, such a person creates a society of envy, and due to this mentality, he plunges into the ocean of suffering. Such a foolish person does not even know about this.

SB 5.5.17 — If someone is ignorant and addicted to the path of saṁsāra, how can one who is actually learned, merciful and advanced in spiritual knowledge engage him in fruitive activity and thus further entangle him in material existence? If a blind man is walking down the wrong path, how can a gentleman allow him to continue on his way to danger? How can he approve this method? No wise or kind man can allow this.

SB 5.5.18 — One who cannot deliver his dependents from the path of repeated birth and death should never become a spiritual master, a father, a husband, a mother or a worshipable demigod.
