No matter how each of us define well-being, what lies in the core concept is a healthy mind in a healthy body, empowered by an indomitable spirit. Yoga brings about this harmonious integration of mind, body and spirit. The term yoga is not only confined to physical postures, but it signifies union with the supreme universal spirit as the word “yuj” which means unity (union of the mind and body). Thirumoolar, a great Saint of Siddha, preached and advocated many Yogic Tantras in his very old Tamil text Thirumathiram.
