Three Gunas
How the gunas influence behavior
The gunas are responsible for the behavior and natural propensities of all living beings. 1) Sattva is pure, without impurities, illuminating and free from sickness.
2) Rajas is full of passion and is born out of thirst or intense desire and attachment. It binds the soul through attachment with action; 3) Tamas is the darkness and the crudeness in man living similar to animals and birds with Lust. It is born of ignorance and the cause of delusion.
