If one becomes Kṛṣṇa conscious, then brahma-bhūtaḥ prasannātmā (BG 18.54), as soon as he becomes Kṛṣṇa conscious, then he becomes joyful, because he has no more enemy. "Everyone is my brother." Therefore he has no fear. If I become enemy to you, you become my enemy. If I am friendly to you, you are my friend. So a Kṛṣṇa conscious person does not see anyone as something other than son of God.
He sees not that only this. "This person is son of God and that person is not son of God," this is lack of Kṛṣṇa consciousness. Every living entity is son of God, therefore one can love, one can actually have the idea of universal brotherhood, only in Kṛṣṇa consciousness, not otherwise. Otherwise, they are simply false propaganda.
Real Kṛṣṇa consciousness, when one achieves, he becomes prasannātmā, joyful. That is the first symptom of becoming full, Kṛṣṇa conscious. Prasannātmā . . . brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54).
He has no hankering. He has no lamentation. Samaḥ sarveṣu bhūteṣu. This is the highest stage of Kṛṣṇa consciousness. Samaḥ sarveṣu bhūteṣu. Samaḥ means equality; sarveṣu, all; bhūteṣu, entities. This is third stage. First stage is joyfulness; second stage is no want, no lamentation; and third stage, to see all living entities on the same . . . paṇḍitāḥ sama-darśinaḥ (BG 5.18).
When one is actually learned, he sees . . . mad-bhaktiṁ labhate parām (BG 18.54). Then he becomes eligible to be a devotee of the Lord.
To become devotee of the Lord is not so easy. These are the conditions. The beginning is joyfulness. The second stage, no want, no lamentation. "My father is Kṛṣṇa, so I'll be fully sup . . ." Just like a child. He knows, "My father is there. I have no want." Everything is there. Prasannātmā. "Why shall I hanker him? My father . . ."
(break) . . . he's now lunatic. Similarly, tiger is my brother, but not that because originally he's my brother, I shall go and embrace. No. I shall be careful. But not that I shall kill. Why shall I kill? He's not coming to encroach upon my property. He's living in the jungle. Why shall I go and kill a tiger?
This is all nonsense, lack of Kṛṣṇa consciousness. He has not done any harm to you. He is living in his own jurisdiction. He is uncivilized. He is ferocious. God has given him direction, "Oh, you live here. You don't go there." That's all right. And why should you go to kill a tiger? He's not coming to encroach him.
