Consciousness is free flow of energy.This energy can be manifest which indicates physically identifiable activity and it can also be unmanifest or physically un-identifiable energy. The human brain function is recognised by observing the outward activity of an individual. The type of activity indicates the level of evolution of a person's character.

Character of an individual is the true indicator of the inner personality of a person. Character is closely connected to the individual consciousness which is influenced by the environment in which the individual lives.

The external environment is equally powerful and acts on the individual constantly.

Hence it is important to get away from the routine of daily humdrum at regular intervals in order to evolve to a better and better state of existence.

In other words the brain has to be rested periodically to make it grow to deeper states of awareness.

Therefore, the human brain is the window through which deeper states of awareness can be viewed and finally experienced.

The human mind needs to be applied constantly to look through and at deeper and deeper states of awareness.
