Master Rinzai said that there is a true person of no rank, always entering and leaving, through our face.
It is tempting to interpret this as fantastical or symbolic, rather than a description of actual experience.
Note that he didn’t say the heart – which extends everywhere – but the face.
People often imagine that underneath all our conditioning is a true person, and the purpose of spiritual practice is to get there, but Rinzai’s expression is entirely contrary to that. The true person is not you. They are not someone else.
It is as if metallic casts of our masks were suspended in Emptiness, like wind chimes.
