English annotation by Vishnudut1926: This is a fundamental research about Assamese Vaishnavism (Vaishnava System of ShankaraDeva-Acharya).
I recommend to read along with more simplified Book, which I have uploaded today - "SANKARADEVA VAISNAVA SAINT OF ASSAM", 1st edition December, 1960.
I have speedread in 2 hours, the Book is perfect especially if you are interested in simple forms of Vaishnavism for masses (for example, Shree Gaudiya-Vaishnavism of Shree Chaitanya) with HariNama Kirtanas and etc.
