Sun, you cannot become identical with the sun. It is so powerful, the temperature is so high and great, that you cannot approach even sun. The scientists say even from so many millions of miles away, if a planet or somebody goes near the sun, immediately he will be burned into ashes. So this is false claim that brahma-bhūtaḥ means one becomes God. No. That means that you come to the light of God. That is also nice, to come to the light of God.
So brahma-bhūtaḥ . . . anyway, if you realize yourself that you are not . . . that brahma-bhūtaḥ means simply to understand that "I am not the material body." To be convinced firmly with all reasons and argument, firmly conviction, this is called faith. Faith is not flickering. One must be firmly convinced. So then you immediately become joyful. Just like if you are implicated with some undesirable affairs and if you, some way or other, your lawyer advises, "Oh, you are free from this implication. The law does not bind you," just like you feel pleasure, "Oh, I'm not in this implication?" "Yes," similarly, as soon as one is convinced that "I am not this material body," then immediately he becomes joyful.
Brahma-bhūtaḥ prasannātmā na śocati (BG 18.54). And what is that joyfulness? There is no lamentation and there is no hankering. If you have hankering, then you are not joyful. If you have lamentation, then you are not joyful. These are the signs. Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati samaḥ sarveṣu bhūteṣu.
And if you are actually self-realized soul, in the light of God, then your treatment will be equal to all living entities. Not that "He is animal," "He is man," "He is black," "He is white," "He's this," "He's Indian," "He's American," "He's Chinese." "He's that." Samaḥ sarveṣu bhūteṣu. Everyone is spirit soul, son of God, part and parcel of God. This realization. Prasannātmā.
