Śrīla Rūpa Gosvāmī wanted to please Sanātana Gosvāmī. Our duty is to please the superior, not the public. We are giving service to the public according to the direction of the superior authority. We do not manufacture any program of service. That is not our business. Whatever is ordered by the . . . just like Caitanya Mahāprabhu. Caitanya Mahāprabhu, He's Kṛṣṇa Himself.
Still, He was following the authorities. Śrī Kṛṣṇa, Bhagavān, the Supreme Personality, He was also referring to the Brahmā-sūtra: brahma-sūtra-padaiś caiva viniścitam. So this is the way, that any bona fide spiritual propaganda must be following the footsteps of previous authority.
At the present moment, it has become a fashion to manufacture some idea. But that is not the Vedic way. Vedic way is to receive the message through paramparā system. Evaṁ paramparā-prāptam imaṁ rājarṣayoḥ viduḥ (BG 4.2). Not to deviate the paramparā. So Sanātana Gosvāmī was taught by Śrī Caitanya Mahāprabhu continually for two months personally in Benares, Vārāṇasī. Therefore he's our authority.
