In depth discussion of Hong Sau - the Breath - Heart Rate Variability

Hong-Sau treated as a breath technique built on the Holy Trinity of Breath: under seven breaths a minute, no pauses, and a slightly longer outbreath, with hot heavy hands and blood leaving the lips as proofs. Includes a Russian astronaut's heart rate variability story, Sisyphus as the breath, and John Selby's two-points route to no mind.
