Bhagwa or the saffron colour denotes renunciation or disinterestedness. Our leaders must be indifferent to material gains and dedicate themselves to their work.
The white in the centre is light, the path of truth to guide our conduct. The green shows our relation to the soil, our relation to the plant life here on which all other life depends. The Ashoka wheel in the center of the white is the wheel of the law of dharma. Truth or satya, dharma or virtue ought to be the controlling principles of all those who work under this flag.
Again, the wheel denotes motion. There is death in stagnation. There is life in movement. India should no more resist change, it must move and go forward. The wheel represents the dynamism of a peaceful change and hence, this deviation does not revolt against the original idea of having a spinning-wheel in the national flag.
