All investigations associated with the mind are delusions of various sorts. They are subjective. All that people do - seeing, hearing, experiencing and doing, are all mental delusions caused by association with the body. The mind cannot keep still even for a moment, without thinking about something or the other. Hence the mind is dependent on the body. All that the mind experiences, relates to the world that is made of the five elements. The mind sees the world through the eyes, hears through the ears. The mind has no form of its own; it is Maya (delusion). It is desire. It is Nature. It is ignorance (Avidya). Delusion is its very nature. It is extremely difficult to understand the pure and immutable Divine Soul (Atma) through an instrument subject to delusions.(Divine Discourse, May 30, 1990.)
