the eagle Scorpio, Cups, Shakti
Water is the earth-bound primary element, the counterpart of the heaven-bound fire.
In a spiritual context, water represents love, joy, and other feelings, and quiet reflection and inner peace. In such a context, water is expressed primarily via the heart chakra.
In Jungian psychology, water represents feeling.
In a mundane context, water represents emotions, fantasy, and passivity. In such a context, water is expressed primarily via the navel chakra.
Like earth, water is yang (dense) in nature, and yin (passive) in expression. Water is more subtle than earth, and also more passive. Water tends towards positivity.
