The heart is something western philosophy has never understood, it seems to me.   The heart is able to open or close.  It can become solar, can receive a spirit that henceforth lives within.   Or at least people who devote themselves to certain practices have this experience.   It is possible to read a book with the heart instead of with the mind, but it’s difficult to explain what that means or what it’s like.    When the heart is open, there are no longer any means, but only ends.   Western philosophy tries to reduce as much as it can to logic or to matter, or to maintain a rather open ended skepticism.   The heart doesn’t seem to fit into any of these categories.   The heart can make contact with genuine knowledge that it cannot explain.
