I am re-reading "Introduction to the PanchaRatra and The Ahirbudhnya-Samhita" by F. Otto Schrader this spring (new enchanced scan - https://archive.org/details/43227700SchraderFOttoPancaratra).
While retelling 45th Chapter of "Shree Ahirbudhnya-Samhita" Otto Schrader notes that Shree Sudarshana-sadhana is so powerful that it eradicates even prarabdha-karma.
No wonder about it because Shree Sudarshana-Vidya is closely connected both with classic Shree MahaLakshmi-Vidyas and orthodox MahaVishnu-sadhanas!
