With some Sahaja Yoginis I started a new program for children (from three to five years old) in a public school and what we do for the moment is some play with the music and songs. We start with natural sounds (water, wind, birds) and after we suggest to the children to relax closing their eyes and trying to feel like a tree inside the wood. We make them listen to the wind (that is Shri Mataji blowing, taken from a CD) and after the tree grows (they stand up and we do some breathing and movements with music).
They enjoy this very much. At the end we raise the kundalini with a little song (that speaks about a butterfly that flies high on the top of the head).
