5. Thomas Cleary (Translator of Indian, Chinese, Japanese Religious Works. 1949-Present)

Go to Amazon and look up The Flower Ornament Scripture or find it at your local library. This is an ENORMOUS work that's over a thousand pages and provides literally a lifetime's worth of philosophy.

7. Alan Watts (Teacher of Taoism, Buddhism, and Eastern Religion. 1915-1973)

Tao: The Watercourse Way, The Way of Zen, and The Book: On the Taboo Against Knowing Who You Are are all excellent for any counter-cultural mind

8. Joseph Campbell (Teacher of Mythology and World Religions. 1904-1987)

The Power of Myth is an excellent collection of essays ranging from explanations on Indian Hindu philosophy, to schizophrenia, to humanity's future. Very concise and readable.


9. Chögyam Trungpa Rinpoche (Tibetan Buddhist Teacher (Kagyu and Nyingma Lineages). 1939-1987.)

The Sacred Path of the Warrior describes a journey to understanding your true self and using this understanding to improve your world.

10. Songyal Mipham Rinpoche (Tibetan Buddhist Teacher (Nyingma Lineage). 1962-Present)

Ruling Your World: Ancient Strategies for Modern Life is a similiar continuation of The Sacred Path of the Warrior which concerns actualizing philosophical insights into your everyday life actions.

This are just the primary ones that strike my mind now, though there are many more.

great, now i'll NEVER be able to get anything done.

Nothing like a trip down the endless rabbit hole of philosophy.
