From R.H. Blyth:
“Thus we see that love of all living creatures which springs up naturally in our hearts, unless thwarted by instruction, custom, or self-love, is no more and no less than our Buddha-nature manifesting itself. Further, love, like knight errantry, equalizes all things, and this equality of all things, the absolute worth and goodness of all that exists or happens, is what Zen aims to make us realize in a practical, concrete way.”
