Beautiful, aren't they? So peaceful.
I see the Tara, esp the Green Tara meditations, as blessing the earth, and therefore blessing the physical self. The 'healing' really enters from this realm. Imagine you have fertilizer, earth, but below, deep. You set a hole in the earth, plant a seed, just right, to plant it (like the sacral chakra); then the sun solar, allowing sun 'in' yet, sun also shines to ground, plant (solar). then the bud, sprout comes out, the heart chakra, rises above the surface, I see this more as seeing the magic of Green Taras face, the healing (like herbs) and heart (glowing green).
