The Fish-Water Metaphor for the True and the False

If the fish is used as a metaphor for illusory dharmas, and the water as a metaphor for the wondrously bright true mind, then the fish cannot be separated from the water, just as illusory dharmas cannot be separated from true dharma. When the fish moves, the water moves; the water stirs up waves. When the fish does not move, the water does not move either, and the waves are calm. When the manas moves, the tathāgatagarbha moves and manifests realms; when the manas does not move, the tathāgatagarbha does not move, and there is the tranquility of nirvāṇa.
