Revatīnandana: "A person is said to be still further advanced when he regards all—the honest well-wisher, friends and enemies, the envious, the pious, the sinner and those who are indifferent and impartial—with an equal mind." (BG 6.9)
Prabhupāda: Yes. This is the sign of advancement. Because here in this material world, the calculation of friend and enemy, everything, is in the relationship with this body, or sense gratification. But realization of God or the Absolute Truth, there is no such material consideration.
Another point is that here, all conditioned souls, they are under illusion. Suppose a doctor, a doctor goes to a patient. He is under convulsion; he's talking nonsense. That does not mean he will refuse to treat him. He treats him as friend. Also, although the patient calls him by ill names, bad names, still he gives him medicine.
(break) Lord Jesus Christ said that, "You hate the sin, not the sinner." Not the sinner. This is very nice. Because sinner is illusioned. He's mad. If you hate him, then how you can deliver him? Therefore those who are devotees, those who are really servant of God, they have no hate for anyone. Just like Lord Jesus Christ, when he was being crucified, he was requesting God, "My Lord, please excuse them. They do not know what they are doing." This is the position of the devotee. Yes. Because they are mad after materialistic way of thinking, so they cannot be hated, anyone.
