I did a guided meditation for spirit guides (find more info on
Shift Your Spirits blog).
I met three guides. I talk to the main one, "Amanda" quite often. She looks like Mia Sara from the movie "Legend" and has an incredibly soothing voice. When I meditate, I often go into the lush forest scene from "Legend" and meet her, plus my other guides.
It's been barely a month since I've "met" my guides, so I'm still trying to figure out what to do. But, yes, you can find your guides through meditation.
