The sending is much easier than receiving, I find. I basically just verbally spoke to my last rescue cat about all sorts of things and in a reading with a communicator regarding a cat who had disappeared not long before, the rescue popped in and gave some very detailed bits that I had verbally discussed with her. So not real rocket science there , but I find getting the mind (and doubting ego) out of the way for receiving more of a challenge.

I have an audio course by Penelope Smith, but I keep delaying starting it. I've enjoyed her books as well.
