Guṇa

'''''' () refers to the three fundamental tendencies or forces that constitute nature, or the matrix of material existence in Hindu philosophies. It can be translated as "quality, peculiarity, attribute, property".

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 (lethargy, violence, disorder). Rajas is innate tendency or quality that drives motion, energy, and activity.

Sattva (Sanskrit: सत्त्व, meaning goodness) is one of the three guṇas or "modes of existence" (tendencies, qualities, attributes), a philosophical and psychological concept understood by the Samkhya school of Hindu philosophy. The other two qualities are rajas (passion and activity) and tamas (destruction, chaos). Sattva is the quality of goodness, purity, positivity, truth, serenity, balance, peacefulness, and virtuousness that is drawn towards Dharma and jñāna (knowledge). The act or a person who bears this is called Sattvic.
