A Free Book

I'd like to share an important book, link below. Does anyone know of the philosopher Aldous Huxley?

The Perennial Philosophy explores the shared metaphysical core found at the heart of all the world’s major religious and philosophical traditions. Huxley argues that beneath differing dogmas, rituals, and cultural expressions lies a universal truth: that there is a divine reality available to humanity, that human beings possess a spark of this divine nature, and that the ultimate purpose of human life is to identify with and directly experience this Supreme Reality. The book compiles writings from Christian, Buddhist, Hindu, Taoist, Jewish and Islamic teachers to demonstrate that this divine level of reality can only be known firsthand through self-transcendence, ethical living, and deep contemplation.
