From Srila Prabhupada:
Tamal Krsna: These two pujaris, the two brothers…
Prabhupada: They’re ideal.
Tamal Krsna: …they look like they’re out of the Caitanya-caritamrta. They appear as two persons right out of that book.
Prabhupada: Yes. Very good boys.
Tamal Krsna: Vaikuntha men.
Prabhupada: Oh, yes. They do not know except the duty. Very good boys.
Tamal Krsna: Perfect team of brothers.

Srila Prabhupada told one of his Mayapur managers, “I have noticed those two brothers. They are wonderful devotees. They never speak nonsense, they’re gentle, and they’re always meditating on Sri Sri Radha-Madhava.
