English annotation by Vishnudut1926: Laconic 16-pages Tantrik Paddhati of Shree Nimbarka-Vaishnava-Sampradaya in Hindi.
Interesting fact - Shree Nimbarkas have 2 Mantras in their sadhana: 1. Prapatti-Mantra and 2. Classic Gopala-Mantra.
It resembles the Mantra pattern of Shree Ramanuja-Sampradaya, because we also have one Prapatti-Mantra and one classic Mantra!
