As the mind evolves, it accumulates. Layers upon layers of structures form on top of each other. They get refined and appear as very refined and sophisticated structures. There appears knowledge, understanding and awareness. But all these layers do is, mask that which is. The reality is distorted and filtered through these evolutionary layers of the mind. Hence they are actually layers of ignorance. We will discuss nine such essential layers with some sub layers. When we know our place in the grand scheme, we can focus our efforts effectively, and therefore can easily transcend these layers, to arrive at that which has no layers, no knowledge and no ignorance.
