As for ""Shree Krishna Yamalam MahaTantram" (uploaded by me in this post and mentioned in this post) in Hindi Exordia it is stated that this is The Book of Chaitanya Sampradaya, the kind of Tantric Paddhati of Chaitanya Sampradaya!
Strange, as I know The Granthas of Chaitanya Sampradaya very well, but I never heard of "Shree Krishna Yamalam MahaTantram", though in Chaitanya Sampradya "Shree Vishnu Yamalam Tantra" and "Shree Rudra Yamalam Tantra" are being cited sometimes.
As for The Tantric Part of Chaitanya Sampradaya, "Shree Brahma-Samhita" and "Shree Hari-Bhakti-Vilasa" are the Primary Granthas. They also have Paddhati, I can't name the Book, as it is the part of their hidden Siddhanta (nothing esoteric and occult here, just the Paddhati with Mantras, Gayatris and Dhyanas, but as All the Tantric Granthas it must be kept hidden from non-deserving people and 99% of "people" in Kali-Yuga are non-deserving, truly speaking).
So, as for the Tantric Paddhati of Chaitanya Sampradaya, it is well hidden and usually designated only for the best shishyas! I know it partially: a lot of Superb Mantras and Dhyanas, though I never had Ruci for Them.
The Most crucial part in Gaudiya Tantric Tradition is GOPALA MANTRAS. So don't be deceived by "Hare Krishna Mantra" chanting, Gaudiya Sampradaya is not so simple, they have Tantric Paddhati and much more Advanced Mantras...
It is also stated in Hindi Exordia, that "Shree Krishna Yamalam MahaTantram" is influenced by "Shree Brahma Vaivarta-Purana" and by "Shreemad Devi Bhagavatam" ("Shree Devi Bhagavata Purana"). No wonder here, as Bhagavan Shree Krishna and Shreemati Radharani Devi are The Heroes of Both The Puranas (though in much, much, much lesser extent in "Shree Devi Bhagavata Purana").
I have no time for looking through the Hindi Exordia further now and I need to study both Exordia and Sanskrit Text in more accurate manner.
And after this I will write the synopsis (it will take about 2-3 years, HEHEHEHE!!!!, as I have the very enormous digital warehouse of Bhakti Books in Hindi and English - 32GB SDHC running out of space - and this Tantra is the last in the list, that is not very interesting to me).
But if someone is initiated in Chaitanya Tradition, he will surely study "Shree Krishna Yamalam MahaTantram"!
