The following is Pramanic List of Granthas cited in Assamese Vaishnavism (all of them being mentioned in "Shree Bhakti-Viveka" by OM VishnuPad BhattaDeva-Acharya).
The list is very profound and astonishing. I am very much interested in "Shree LaghuBhagavata", "Shree Varaha-Rahasya", "Shree Brihat Vishnu-Samhita" and "Shree Vishnu-Yamala" (you can click the below picture to enlarge):
You can notice "Shree Vishnu-Rahasya" in the list.
A.C.BhaktiVedanta Swami PrabhuPada, The Acharya Who granted Krishna Consciousness to the Western world, cites "Shree Vishnu-Rahasya" in "The Nectar of Devotion", He writes:
"In the Kātyāyana-saṁhitā it is stated that even if one is forced to live within a cage of iron or in the midst of a blazing fire, he should accept this position rather than live with nondevotees who are through and through against the supremacy of the Lord.
Similarly, in the Viṣṇu-rahasya there is a statement to the effect that one should prefer to embrace a snake, a tiger or an alligator rather than associate with persons who are worshipers of various demigods and who are impelled by material desire".
