The other day I received an e-mail request from a college student for some suggestions related to Eastern religions. For what it's worth, what follows is the substance of the e-mail reply I sent. My goal was simplicity, rather than a lengthy bibliography. Anyone reading this with better suggestions is invited to offer them in the comments section of this post. Thanks!
Dear Sarah,
I hope you had a good weekend... You asked about a Christian perspective on Eastern religions. You might want to have a look at chapter 11, "Christianity and Religion" in C.S. Lewis's book Miracles. I am sure it is readily available in your university library.
Another suggestion would be to have a look at Os Guinness's book, The Dust of Death, ch. 6 "The East, No Exit." Especially valuable would be pages 211-231 where Guinness discusses the perspective of monism under three heads: "Monism and Reality," "Monism and Personality," and "Monism and Morality." Out of curiosity I just checked the internet and see that there's a paper available that draws heavily on Guinness. It looks fairly useful at a quick glance. It can be found here.
As far as other internet material is concerned, at one time I had a considerable amount of such information, but then I had a hard drive failure and lost it all. What comes most immediately to mind, however, is a book that Vishal Mangalwadi wrote and which he has made available in its entirety on the internet - When the New Age Gets Old: Looking for a Greater Spirituality. It is now out of print. For some reason the online version failed to include the "Table of Contents." I have a copy of the book, and so I can provide the Table of Contents here:
1) The Universe in the Human Mind: The Background to New Age Thought
2) Let Us Make Man in the Image of His Stars: Astrology and the New Age
3) Spiritism
4) UFOs - A Religious Experience
5) Tantric Sex: A Celebration of Life?
6) Doing Ecology is Being Human
7) Vegetarianism: Self and Selfishness
8) The Reincarnation of the Soul
9) My Course in Miracles
Epilogue: Finding Ourselves
Appendix
Notes
Mangalwadi also has an 18-page paper available on the internet titled Yoga: Five Ways of Salvation in Hinduism I hope these suggestions will prove helpful. Every blessing!
