ok what i am getting here is ,
1. you are trying to hard,,
they say if you try to hard, when they speak you might miss it .
2. they say have no expections,
for the longest time i been expecing to see my guides glow in front of me, or talk in a voice besides my ear
hey holmes, yada yada yada.
so if you expect them to approach you in a movie style way or in a certain way , that can block them too.
3. and to clairify that point,
the way you are connecting might not be your speciality and so you have to gauge what clairsense is the best for you (divine guidance by doreen virtue or , you are pyschic book by pete a sanders, jr, will help you understand ) .
4. somestimes the mind itself can block us,
and the key to starting it is to pretend the guide is speaking, and you will begin to say hey i am getting something am i making it up.
5. perhaps your feelings are blocking the way .
feelings of self worth, or specialness.
we are worthy , and we are all special in the eye of the high level guide.
6. if the fears block your way ,
explore them too, and perhaps read opening to channel (one book i highly reccomend, ) ask your angels, and how to talk to your angels,
and divine guidance,
(check your library ) .
