My interest in India I get from my father, who studied eastern philosophy with Sahakian in college. My father never traveled to India, but told me of a friend and classmate who did; the poor fellow got off the plane, looked around, and got right back on and returned to the US. (I am not sure if this classmate changed his major, and the only other thing I remember about him is that he had a cat with horrid scars from going through the dryer accidentally.)
My first teacher was an Indian woman (a Buddhist married to a Brit) who ran an excellent pre-school in Boston. I was but three years old, but remember the school vividly; it was wonderful. Thank you, Mrs. Renfrew!
In addition to the books here, I recommend rounding out a study of India with a visit to an Indian restaurant or grocer. We do, often...Remember this post about Paul's discovery of Sweet Paan? That was a fun thing to try (once).
