मनस् - mAH-nuhs

The perceiving mind. [ref]Essence of the Bhagavad Gita, explained by Paramhansa Yogananda. Glossary.[/ref]

Also referred to as monmanas is one of the four aspects of consciousness. Whether a person is identified with ego consciousness of cosmic consciousness, his perceptions of the world are mediated through manas. [ref]Essence of the Bhagavad Gita, explained by Paramhansa Yogananda. Chapter 19, “Knowledge and Wisdom.”[/ref] The other three aspects of mind are buddhi (intelligence), ahankara (ego), and chitta (feeling). [ref]God Is for Everyone, by Swami Kriyananda. Chapter 10, “The Science of Religion.”[/ref]

The first aspect of perception, manas shows a person how the world appears through the instruments of the senses. Manas does not qualify or define the images. At the conscious level of manas, the person is not yet involved in the delusions of ego identifications or involvements. [ref]Intuition for Starters, by Swami Kriyananda. Chapter 5, “How to Recognize False Guidance.”[/ref] Through the senses, impressions enter and are stored by manas in a passive way. The information remains a confused and disconnected mass until it is further processed by other aspects of consciousness. [ref]Science of Religion (1924 Edition), by Paramhansa Yogananda. Chapter 3, “Instruments of Knowledge.”[/ref]

The consciousness of manas is centered at the top of the head, whereas the other three aspects of mind are centered on progressively lower parts of the human body. [ref]Demystifying Patanjali, by Swami Kriyananda. Book 1, Sutra 2, “Yoga is the neutralization of the vortices of feeling.”[/ref]
