If they don't, they are not

Gurudas : I said to Prabhupada, "Gaurachandra Goswami is in a goswami family, but he doesn't want his son to eat prasadam with us." Prabhupada said, "Yes. You can find out how they really feel about us in Vrindavan by inviting them to prasadam. If they come, they are for us. If they don't, they are not."
