Gunas

The three fundamental qualities, gunas, or tendencies which underlie all manifestations are sattva, rajas and tamas. The sattva represents purity and is free from all evils. A sattvic person is wise, helpful and has equanimity. The raja is activity. A rajasic person relentlessly pursues his goals; he is ambitious. Tamas is born out of ignorance. It makes one work under the compulsion of the body, without applying power of judgment. A tamasic person is averse to work or activity. It is the mix of the gunas which differentiate one person from another
