Ed is an old guy living on social security and very rare work editing. He spends most of his time studying himself, Robert Adams and Nisargadatta, and writing about them and himself for his students and readers. Satsangs are free on Sunday, as are all these posts answering students' questions. His single book is posted free on wearesentience.com, his website, and queries are answered by email, on his blog, or Facebook. He takes care of his own 7 cats at home, and helps feed several hundred homeless cats in Los Angeles. The cats need the money to eat and so does he in order to help you. Do not feel obligated, only if you are so moved.
