I think an interested reader can get a lot of Gravity & Grace (which I recently completed) without much background in philosophy so long as one accepts that they won't understand _everything_ she writes.

That being said, the Iliad and Bhagavad Gita seem as important to her work as more recent philosophers like Hume.
