Our concept of the shape of water depends on the state of water and what contains the water. When we see the water in a bottle, we unconsciously shape the water into “bottle”; when we see the water in a cup, we unconsciously shape the water into a “cup”; when the water is on the ground, we unconsciously shape the water with the “terrain”; when the water is frozen, we unconsciously shape it with a new name “ice”; when the water becomes cloud, we unconsciously forget it is still “water”…… but for water, there’s no boundary.
We shape the gathering of four elements (earth, water, fire, wind) into “my body”, we shape the four aggregates (feelings, perceptions, mental formations, consciousness) into “my mind”, we shape the dependent arising phenomena into “my life”, they are all contained by “mine” – an illusive inherent container. It is like a dam containing the endless things even more than an ocean. It is cemented by the illusion of “inherent self”, which builds up the boundary, isolates us from the wholeness and partition off the connection with the real Nature – “no inherent self”. Both happiness and suffering exist based on their “inherent self” and cling to their own boundary.
When we begin to doubt that the “inherent self” might not be real, the cementation will start to loose its glutinous power, the dam of “mine” will become thinner and looser. Until when we realize and experience the “no inherent self” in everything directly, the dam will suddenly collapse.
We call it “Emptiness” – the connecting with the whole, the breaking of limitedness. And don’t imagine there’s a Oneness that can be grasped either!
