If one corner of the ARC triangle is knocked out the remaining corners also get knocked out. Here, a child cheerfully approaches his mother to give her a flower. Preoccupied with housework, the mother ignores the child's communication, which becomes knocked out, followed soon after by less affinity and less reality. The third and most important corner of the ARC triangle is communication. In human relationships this is more important than the other two corners of the triangle in understanding the composition of human relations in this universe.
Communication is the solvent for all things.
It dissolves all things. In order for there to be communication, there must be agreement and affinity. In order for there to be affinity, there must be agreement on reality and communication. If you knock affinity out, communication and reality go. If you knock reality out, communication and affinity will go.
