Calling On Your Angels

The function of Angels is to provide us with our spiritual
and emotional needs. Basically speaking, they take care of us.
Angels work primarily on the emotional plane, but once we're
open to them, we can feel their presence around us all the time.

How do you contact my Angels?

It is very simple to contact your Angels.
All you need to do is call them.
Many people choose to construct an alttar, meditate,
light candles, burn incense... there's as many ways to
contact Angels, as there are people.
It's all personal preference. Even though these techniques
may set the stage, make you more comfortable and make
the Angels feel welcomed, this is not necessary.
All you need to do is call out to them.
It doesn't have to be in words, all it needs to be is a thought
"Angels, I need your help."  They always come.
If you open yourself up to their energy, you will feel their presence.
