Once in Śrī Dhāma Māyāpura at Śrī Caitanya Maṭh library Śrīla Prabhupāda was there doing some vāṇī-sevā, suddenly he started shouting— “Nobody here! Nobody here!” Śrīla Gurudeva (who then was known as Pranavanada Brahmacārī) Bhakti Pramode Purī Gosvāmī Mahārāja heard his voice and started running towards the library to help Prabhupāda if needed. But he discovered that nothing happened, only because the eldest daughter of Śrīla Saccidānanda Bhaktivinoda Ṭhākura, who was then around 65 years old lady, came to meet with him (Śrīla Prabhupāda) alone—which is strictly prohibited for a sannyāsi ācārya. All the complete teachings of Śrīmān Mahāprabhu were found in the jivan līlā of Śrīla Prabhupāda Bhakti Siddhānta Sarasvatī Gosvāmī Ṭhākura in applied form which is really very very rare.
