Yoga Sutras (can’t wait until you come out with your interpretation book!). III 48 Samyama on the senses. Is it talking about the role of the senses? Directing perception (eg my perception of an object or sound, etc?) Exploring all pervasiveness (is that my "entering into the object to explore what makes it tick?) Indifference (not becoming attached?).
The idea is to discover the distance of mind and senses. Do not let mind react to sensory inputs. Just tone as it were the witness consciousness muscles.
