Bha representing the emotional intelligence, which is an embracing form of intelligence unlike the intellect which is more of a dissecting kind. The Eastern cultures have always held the emotional intelligence as more significant as it is inclusive in nature. It is more life oriented and less about being better than someone else. It is about finding a beautiful expression to human possibility versus being a winning rat.
Ra – represents Raga or the tune of life. This is not our business but set by the source of creation or the Divine. Just learning to keep in tune with it is the ultimate form of knowing.
Tha – represents the rhythm, to find a rhythm that makes us individuals but all playing by the same tune. Knowing the universality of our existence at the same time giving expression to an individual exuberance that is unique.
This is not only the Dance form but the name taken upon by a culture hence the very nation has always been referred to as Bharata Varsha meaning a shower or cascade of Bhava, Raga, Thala.
