The Supreme Personality of Godhead, who is the greatest—God is great—but He has taken the service of a devotee as a menial driver. So this feeling gave him in ecstasy. This is a sign. It is not artificial. Tad guṇa-sūnavan, er, śruti-mātreṇa (SB 3.29.11). Just like if you place . . . if you pour some water on the ground, you will see where there is down level, it will at once go to that side. Without any arrangement, you simply pour the water and it will go down where the level is down, just like the rivers are flowing to the sea level. Similarly, a highly developed Kṛṣṇa conscious person, at once he will hear about something of Kṛṣṇa, he will be in ecstasy.
Just like Caitanya Mahāprabhu. There was a devotee of Caitanya Mahāprabhu. His name was Murāri Gupta. He was physician to the then Nawab, Muslim Nawab. Now, they were sitting. The Nawab was going some hunting excursion or something like that, but he was Nawab's physician. He was to accompany him. So they were sitting on the back of the elephant. In the meantime, that Murāri Gupta saw one peacock, and as soon as he saw the peacock, the feather, he at once remembered Kṛṣṇa and at once fainted and fall down.
