Śrīla Bhakti Vinod Ṭhākur’s commentary on the eighth verse of Śrī Upadeśāmṛta.
The following is a translation of Śrīla Bhakti Vinod Ṭhākur’s poetic Bengali translation, Bhāṣā, and Bengali prose commentary, Pīyūṣa-varṣiṇī-vṛtti, on Śrīla Rūpa Goswāmī Prabhu’s Śrī Upadeśāmṛta.
These texts were published in Śrī Gauḍīya Darśan, in Volume 2, Issue 11, 10 June 1957, Volume 2, Issue 12, 12 July 1957, and Volume 3, Issue 1, 12 August 1957. In combination with Śrīla Bhakti Siddhānta Saraswatī Ṭhākur’s Anuvṛtti, they were also published as a book from Śrī Chaitanya Sāraswat Maṭh by Śrīla Bhakti Sundar Govinda Dev-Goswāmī Mahārāj in 1970.
“The Upadeśāmṛta of Śrīla Rūpa Goswāmī is also extremely good for us; we published Upadeśāmṛta before.”
—Śrīla Bhakti Sundar Govinda Dev-Goswāmī Mahārāj,
