Cognition is the world. When you stand in front of the stove, the fish is just an ingredient; when you stand in front of the Buddha hall, the fish is life; when you stand in front of the stall, the fish is a commodity; when you stand by the riverbank, the fish is a scenery. The world you see is never the world itself, but your own cognition and perspective. With different viewpoints in the mind, the world appears in different forms.
