In our meditation this weekend we used this gesture, putting our hands into the air and visualizing light coming through them. It was very powerful, and we alternated that with our hands in the prayer position at the heart. It was meant to help us see our hands as strong, healing, light-giving hands.
The Retreat focus was Key 6, The Lovers, which symbolizes the astrological sign of Gemini. As a person with four planets in the sign of Gemini, I found this weekend very affirming.
