In plain words
Know that the heart which lies within the chest, in one place in a body bounded by measure, is the one to be rejected. But the Heart that is awareness alone is held to be the one to be accepted. It is within and without, and yet it is neither without nor within.
Word for word
In the body bounded by measure, that which is inside the chest: know that heart, situated in one place in the body, as the one to be rejected. But the Heart which is awareness alone is held as standing to be accepted. It is within and without, and not without and not within.
