Ayurveda and Yoga are built on the philosophy of the three gunas: sattva, rajas and tamas.
These concepts represent the qualities that are present in food, nature and actions, as well as our body and mind.
Rajasic means activity, restlessness, stress and anger.
Tamasic means lethargy, dullness and laziness.
Sattvic means balanced, harmony, purity, health and wellbeing.
In each of us there is a proportion of each Guna. Without Tamas we would not sleep and without Rajas we would lack dynamism and without Sattva life would be uninspiring and without the higher human qualities.
The food we eat has an enormous influence on us physically, mentally, emotionally and spiritually.
