The National Flag of India was adopted in its present form during an ad hoc meeting of the Constituent Assembly held on the 22 July 1947, a few days before India's independence from the British on 15 August, 1947.
The flag is a horizontal tricolour of "deep saffron" at the top, white in the middle, and green at the bottom. In the centre, there is a navy blue wheel with twenty-four spokes, known as the Ashoka Chakra, taken from the Ashoka pillar at Sarnath. The diameter of this Chakra is three-fourths of the height of the white strip. The ratio of the width of the flag to its length is 2:3 Each colour in the flag represents something different. the saffron stands for purity and spirituality, white for peace and truth, green for fertility and prosperity and the wheel for justice.
"Bhagwa or the saffron colour denotes renunciation of 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 Chakra" in the centre of the white is the wheel of the law of dharma. Truth or satya, dharma or virtue ought to be the controlling principle of 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."
