The Pratyupanna Samadhi Sutra & The Surangama Samadhi Sutra

Rating:
Summary: Phooey!
Review: This is NOT "The Surangama Sutra", which I misled myself into purchasing.

On it's own merits? Hung up on rituals, as in circumambulating an alter all day, every day, for 90 days. Only of interest to those in Japanese Tendai practice. I don't think so.
