I found another easily accessible reference for learning to communicate with our guides is author and doctor... Doreen Virtue. Her books etc can be found in bookstores everywhere. it's primarily her thing. Her divination cards are beautifully illustrated by numerous artists and I found helped clarify communication when I first started learning "processes". (I had been receiving all my life but needed to find a way of confirming what my belief system was leading me too and find common ground with others. So I prayed for a teacher to appear that would help sort things out for me. Shortly thereafter my attention was directed to one of Doreen's books) I believe The Universe LOVES to communicate with us and does so in so many ways. Guides can be ascended masters and angels/messengers (Jesus, Buddha, Sanat Kumara, Sulis,Brigit. etc), animals (on this planet in our daily lives or in our intuitive realms), sychronistic moments that shed light on issues we're trying to figure out, that still small voice we so often don't hear because of this world's distractions....believe me, guiding spirit is with all of us, always, it's a matter of us learning to listen : )) I enjoy far too many experiences daily to be able to share everything in one reply...but I do feel strongly that once we believe they're already communicating with you , one will begin to "see' their own evidence. Keep the faith, stay in the light, and remember Energy Follows Intent!
