Sannyasa is for the highest qualified brahmana

“Prabhupada: Vaishnava is not so easy. The varnashrama-dharma should be established to become a Vaishnava. It is not so easy to become Vaishnava.
Hari-sauri: No, it’s not a cheap thing.
Prabhupada: Yes. Therefore this should be made. Vaishnava, to become Vaishnava, is not so easy. If Vaishnava, to become Vaishnava is so easy, why so many fall down, fall down? It is not easy. The sannyasa is for the highest qualified brahmana. And simply by dressing like a Vaishnava, that is… fall down. . . . .”
