Guna
There are three gunas, according to this worldview, that have always been and continue to be present in all things and beings in the world. These three gunas are called: sattva (goodness, constructive, harmonious), rajas (passion, active, confused), and tamas (darkness, destructive, chaotic).
Sattva — goodness, constructive, harmonious
Rajas — passion, active, confused
Tamas — darkness, destructive, chaotic
All the 3 Gunas are present in all living creatures as per Gita. The level of each guna varies. Focusing or increasing sattva in ourselves will help in realising of the Self.
In Bhagavad Gita, Chapter 18, verse 23–25, we get more details on the Gunas as thus: Action that is virtuous, thought through, free from attachment, and without craving for results is considered Sattvic; Action that is driven purely by craving for pleasure, selfishness and much effort is Rajasic; Action that is undertaken because of delusion, disregarding consequences, without considering loss or injury to others or self, is called Tamasic.
According to Sankhya school, no one and nothing is either purely Sattvik or purely Rajasik or purely Tamasik. One’s nature and behavior constitute a complex interplay of all of all three gunas, 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.
In Indian mythology, Vishnu is envisioned with more Sattva, Brahma with more Rajas, and Shiva seen with all three Gunas.
