One becomes Two
The next step is for One to become Two. This construct is a process that stems from self analysis. The product of analysis becomes definition. Definition is based on paradigm.
The human mind is programmed to think that the Two comes from division of the whole. A simple slice on the chopping block and the whole becomes two halves. Each half is thought to complete and balance the other. Yet, in accepted reality, time and again, are not the sum of two independent halves often greater than the whole?
This is the beginning of the nature of duality. This is the precept of paradox. In our world, we observe and experience examples of duality and paradox every day.
