If you take the time everyday to go through the thanksgiving address and really focus on these things both in your “minds eye” and your normal senses, it really opens you up to hearing from other-than-humans. The Kamana program has a really good section on it. I used to do the “TGA” every morning to my backyard. It worked well to set my awareness of other-than-humans for the whole day.
