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
The other two qualities are Sattva (goodness, balance) and Tamas (destruction, chaos)
Rajas is innate tendency or quality that drives motion, energy and activity
Rajas is sometimes translated as passion, where it is used in the sense of activity, without any particular value and it can contextually be either good or bad
Rajas helps actualize the other aforementioned two gunas
