That is the position of Krsna consciousness. They are not heartless. They are very submissive.
Bhagavad-gita As It Is Lectures
A devotee is taught to address all his contemporaries as "Prabhu, my dear sir, my dear lord." That is the position of Kṛṣṇa consciousness. They are not heartless. They are very submissive.
Lecture on BG 7.18 -- New York, October 12, 1966: So showing respect to the constable in the street means showing respect to the government, not to that particular person. So these things are there in the Vedic literatures. But if you want some favors from the police officer, then you are also entangled, and that police officer is also entangled. You have to go by the rules. But one who is directly in touch of the Supreme Lord, they do not require to worship any other... Because actually... Suppose a man is personally in contact with your President Johnson. That does not mean he'll disobey the constable. No. Naturally he will obey, although he's direct contact. Similarly, those who are in direct contact with the Supreme Personality of Godhead, they have no disregard for these demigods, but they know the ultimate supreme power is the Supreme Personality of Godhead. They have got that knowledge. So their surrender is there in the Supreme Lord, not here. But they are not going to show any disrespect. A real devotee, he does not show any disrespect even to the ant, and what to speak of the demigods, because he is in knowledge that "Every living entity is part and parcel of the Supreme Lord. They're playing different parts only. So in relationship with the Supreme Lord they're all my respectables." Therefore a devotee is taught to address all his contemporaries as "Prabhu, my dear sir, my dear lord." That is the position of Kṛṣṇa consciousness. They are not heartless. They are very submissive. There are six, twenty-six qualifications of a factual devotee of the Lord. They are very kind. They are very obedient. They are sober, economic, everything, all good qualifications. Yasyāsti bhaktir bhagavaty akiñcanā sarvair guṇais tatra samāsate surāḥ [SB 5.18.12]. One, if he becomes the devotee of the Lord, all good qualities automatically will develop because he is good. By nature a living entity is the perfect good, but due to the contamination of the lust, he has become vicious. He has become vicious. By nature he's not vicious; he's perfect. Because he's part and parcel of the gold, he's gold. By outward covering he has become something nonsense. So this is the process. We are trying to, I mean, to introduce in the modern society Kṛṣṇa consciousness, and that will make us all-perfect, happy, and after leaving this body we shall enter into the kingdom of God, where there is eternal life, bliss and full knowledge.
