In general, then, the way of seeing mountains and waters differs according to the type of being that sees them. In seeing water, there are beings who see it as a jeweled necklace. This does not mean, however, that they see a jeweled necklace as water. How, then, do we see what they consider water? Their jeweled necklace is what we see as water. Some see water as miraculous flowers, though it does not follow that they use flowers as water. Hungry ghosts see water as raging flames or as pus and blood. Dragons and fish see it as a palace or a tower, or as the seven treasures or the mani gem. Others see it as woods and walls, or as the dharma nature of immaculate liberation, or as the true human body, or as the physical form and mental nature. Humans see these as water. And these different ways of seeing are the conditions under which water is killed or given life.
