Rainbow crystal, leaf
Light is an important Yang component in rooms. Crystals break down white light into its components. The resulting rainbow colours stimulate, build up the Chi and enchant with their sparkling glitter.
It also helps to stop energy loss.
Especially in door-window oppositions, it provides calm and stability. Inanimate, dark corners are activated. In long corridors, they slow down the sha-chi. Edges with cutting chi are defused.
