The mind also has its energy and Prana. This derives from food, breath and impressions externally. Prana governs the intake of sensory impressions. Samana governs mental digestion. Vyana governs mental circulation. Apana governs the elimination of toxic ideas and negative emotions. Udana governs positive mental energy, strength and enthusiasm.
Apana on a psychological level governs our ability to eliminate negative thoughts and emotions. When deranged it causes depression and we get clogged up with undigested experience that weighs us down in life, making us fearful, suppressed and weak.
Samana Vayu gives us nourishment, contentment and balance in the mind. When deranged it brings about attachment and greed. We cling to things and become possessive in our behavior.
Vyana Vayu gives us free movement and independence in the mind. When deranged it causes isolation, hatred, and alienation. We are unable to unite with others or remain connected in what we do.
Udana gives us joy and enthusiasm and helps awaken our higher spiritual and creative potentials. When deranged it causes pride and arrogance. We become ungrounded, trying to go to high and lose track of our roots.
