On the mind

In a new environment the mind fights to adapt to the environment. This is the agitated mind.

It continues fighting but slowly starts giving up if it starts finding that it is not adapting inspite of its efforts.

If the fight continues but it cannot adapt, the mind gives up. This is the stage when the mind cocoons itself and goes into a shell to protect itself. This is the closed mind. Until the next suitable environment, the mind remains cocooned and protected. Inspite of all efforts from intelligence, the cocooned mind will not come out of its shell until it finds suitable environment.
