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

Samkhya Philosophy
In Samkhya philosophy, a is one of three "tendencies, qualities": sattva, rajas and tamas. This category of qualities has been widely adopted by various schools of Hinduism for categorizing behavior and natural phenomena. The three qualities are:- Sattva is the quality of balance, harmony, goodness, purity, universalizing, holistic, constructive, creative, building, positive attitude, luminous, serenity, being-ness, peaceful, virtuous.
- Rajas is the quality of passion, activity, neither good nor bad and sometimes either, self-centeredness, egoistic, individualizing, driven, moving, dynamic.
- Tamas is the quality of imbalance, disorder, chaos, anxiety, impure, destructive, delusion, negative, dull or inactive, apathy, inertia or lethargy, violent, vicious, ignorant.
According to the Samkhya school, no one and nothing is either purely sattvik or purely rajasik or purely tamasik. One's nature and behavior is a complex interplay of all of these, with each guna in varying degrees. In some, the conduct is rajasik with significant influence of sattvik guna, in some it is rajasik with significant influence of tamasik guna, and so on.
Bhagavad Gita
The Bhagavad Gita describes sattva as a path to liberation. It describes sattva as superior to the other two gunas because it brings clarity, leads to higher realms, and is without impurities, but it is also described as a cause of bondage. Verse 14.6 describes sattva as:It causes bondage, as explained in verse 14.9, by attachment to happiness.
