The National Flag of INDIA

The Indian flag is a horizontal tricolor in equal proportion of deep saffron on the top, white in the middle and dark green at the bottom. The ratio of the width to the length of the flag is two is to three. In the centre of the white band, there is a wheel in navy blue to indicate the Dharma Chakra, the wheel of law in the Sarnath Lion Capital. This center symbol or the 'CHAKRA' is a symbol dating back to 2nd century BC. Its diameter approximates the width of the white band and it has 24 spokes, which intends to show that there is life in movement and death in stagnation. The saffron stands for courage and sacrifice; the white, for purity and truth; the green for growth and auspiciousness.
The Constituent Assembly which drew up the Constitution of India, adopted, on 22 July 1947, the tricolor as Independent India's National Flag. After a debate, the Dharma Chakra (of Emperor Ashoka) was included in the central white stripe of the flag, instead of the Charka (used symbolically by Gandhiji and also included in the flag used by the Indian National Congress). The same Chakra adorns the State Emblem adapted from the Sarnath Lion Capital of Ashoka in addition to the motto from the Mundaka Upanishad, Satyameva Jayate which means: Truth alone triumphs. The Chakra or the wheel symbolizes the Power of the State governed by Dharma, which is the primordial Indian system of justice which is the bed-rock, not only of governance but of the socio-politico-economic edifice itself.
