Ongoing comments on Yoga Sutra at Baba Rampuri website
In these sutras and some tantric styles of composition, the references are NOT to ideas, but syllables, and indeed syllables appear where there were none, through decompression, as if we would unzip files on a computer. And the syllables, in turn have references. A master of grammar & composition can send the references in many directions at the same time. Patanjali was such a master.
