Rajas (Sanskrit: रजस्) is one of the three guṇas (tendencies, qualities, attributes), a philosophical and psychological concept developed by the Samkhya school of Hindu philosophy.
This category of qualities have been widely adopted by various schools of Hinduism for categorizing behavior and natural phenomena.
[9] In the fourteenth chapter of the Bhagavad Gita, rajas is described as being of a passionate nature, driving desire, attachment, and action.
When rajas is dominant, it manifests as greed, restlessness, agitation, and constant engagement in actions, which obscure wisdom and keep one bound to the cycle of worldly pursuits.
[13] Rajas is that quality or attribute in a substance (prakriti) or individual which promotes or upholds the activity of the other aspects of nature (prakriti) such as one or more of the following: If a person or thing tends to be extremely active, excitable, or passionate, that person or thing could be said to have a preponderance of rajas.
