The Three Gunas

Yoga suggests that there are three major qualities of human temperament:

Tamas	Dullness	Aversion, sloth, ignorance, inertia, and depression.
Rajas	Excitement	Desire, reaction, restlessness, over-excitement, and mania.
Sattva	Balance	Holistic health, integration, consistency, mind, intelligence, sanity, and wisdom.

TAMAS	DULLNESS. Aversion, ignorance, inertia, dullness, depression Too much passivity/yin (overactive parasympathetic nervous system)
RAJAS	EXCITEMENT. Desire, lust, excitement, movement, mania. Too much activity/yang (overactive sympathetic nervous system)
SATTVA	BALANCE. Balance, rhythm, intelligence, unity, harmony, and transcendent considerations. The Golden Mean (holistic health and a healthy nervous system)

The proportion of gunas within our system is dependent upon our holistic diet - the health and input into our system through each chakra.

For self development purposes we aim for a holistically sattvic diet.

The primary ways in which our chakras are influenced by the gunas are:

In terms of the Yoga Gunas, the Selfish Ego thrives on Tamas (selfish aversion) and Rajas (selfish desire) gunas. This is why the Enlightened inform us to create and maintain a Sattvic, Spiritual lifestyle. Then we will be less entangled with the Selfish Ego and create an inner space to analyze, understand, purify, and overcome it.
