English annotation by Vishnudut1926: The Grantha from Shree Ramanandi-Vaishnava-Sampradaya.
The distinctive trait of this Grantha is dwelling on "Shree Hanuman-Chalisa" as what I would name as "anti-calamity-upaya" (recited either 49 or 108 days).
If you are well-versed in Vaishnava Tantras and Agamas, you probably know, that all Hanuman-related sadhanas are usually being used against severe bandhas of all kinds (prison, Saturn and etc.)
If not, than you can find details regarding such upayas in any Hanuman-related Tantra and in some Puranas.
