Sattva is the third guna, representing purity, harmony, and balance. It is subtle, sublime, clear, neutral, and pure, characterized by qualities of clarity, lightness, and serenity. Sattva promotes mental clarity, emotional stability, and a harmonious relationship with oneself and others. It contrasts with Rajas (activity) and Tamas (inertia); Rajas is dynamic and passionate, while Tamas is heavy, confused, concealed, slow, unwavering, and persistent. Understanding and cultivating Sattva is essential for spiritual growth, facilitating introspection, meditation, and the pursuit of higher knowledge.
