The Perennial Philosophy is primarily concerned with the one, divine Reality substantial to the manifold world of things and lives and minds. But the nature of this one Reality is such that it cannot be directly and immediately apprehended except by those who have chosen to fulfil certain conditions, making themselves loving, pure in heart, and poor in spirit. Why should this be so? We do not know. It is just one of those facts which we have to accept, whether we like them or not and however implausible and unlikely they may seem.
