With the Akshobhya Buddha (the unshakeable one) and the healer 'Blue Buddha,' blue symbolizes serenity, ascension, the infinite, purity, and healing. In general, blue reflects wisdom, but light and dark blue have distinct meanings. The light hues that Buddhists meditate upon represent the limitless heights of ascension, and the dark opaque blue as earth - holding the wisdom of the earth and sky within it. Simultaneously, they embody the duality of living and dying.
