If you really want even more help in communicating with your angels and receiving their messages, there is a book called:
HOW TO HEAR YOUR ANGELS: by doreen virtue.
Amazon.com: How to Hear Your Angels (9781401917050): Doreen Virtue: Books
This book goes into great detail on what to do to know, see, feel and hear your angels guidance. There is also discussion on how to tell the angels voice vs false guidance.
Also, she explains (and this was new news for me as well!) that having a clean 3rd eye is NOT enough to get clear guidance. On page 131, she says without the connection between the 3rd eye and the occciptal lobe, a person will NOT be aware of or understand his/her visions. She said it is like showing a movie without the projector light on! Then she goes on to explain in detail the 7 steps to opening your 3rd eye (I am definetly doing these!).
There is also discussion on how to heal from psychic blocks from past lives that may be preventing you from receiving guidance clearly. As well as discussion on the whole host of other things that could be getting in the way of receiving clear guidance (like poor diet, not exercising, stress, being in a toxic environment, etc).
