Pradyumna: "They belonged to the highly situated sārasvata-brāhmaṇa community, but they were ostracized due to their acceptance of ministerial posts in the government of Hussain Shah. It is the grace of Lord Caitanya that He accepted these two exalted personalities as His disciples..."
Prabhupāda: The brāhmaṇa community was so strong that because acceptance of service is the business of the śūdra... The brāhmaṇas, they would not accept anyone's service. The kṣatriyas, they would not accept anyone's service. And the vaiśyas also. They should live independently. Brāhmaṇas, by culture of Vedic knowledge. Kṣatriyas by exacting taxes from the citizens. And vaiśyas by trade, agriculture. They should live. To serve one is the business of the dog. That is mentioned in Bhāgavata. So if there is dire necessity, a brāhmaṇa can accept the profession of a kṣatriya or the, even the profession of a vaiśya, but not the profession of a śūdra. But at the present moment, because everyone accepts the profession of śūdra, therefore śāstra says: kalau śūdra-sambhavaḥ.
