The Ashoka Chakra (the wheel of Ashoka) is a depiction of the Dharmachakra or Dhammachakka in Pali, the Wheel of Dharma (Sanskrit: Chakra means wheel). The wheel has 24 spokes. The Ashoka Chakra has been widely inscribed on many relics of the Mauryan Emperor, most prominent among which is the Lion Capital of Sarnath and The Ashoka Pillar. The most visible use of the Ashoka Chakra today is at the centre of the National flag of the Republic of India (adopted on 22 July 1947), where it is rendered in a Navy-blue colour on a White background, by replacing the symbol of Charkha (Spinning wheel) of the pre-independence versions of the flag. Ashoka Chakra can also been seen on the base of Lion Capital of Ashoka which has been adopted as the National Emblem of India. The Ashoka chakra was built by Ashoka during his reign. Chakra is a Sanskrit word which also means cycle or self repeating process. The process it signifies is the cycle of time as how the world changes with time. The horse means accuracy and speed while the bull means hardwork. A few days before India became independent on August 1947, the specially constituted Constituent Assembly decided that the flag of India must be acceptable to all parties and communities.[6] A flag with three colours, Saffron, White and Green with the Ashoka Chakra was selected. Sarvepalli Radhakrishnan, who later became India's first Vice President, clarified the adopted flag and described its significance as follows: 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 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. It also represents 24 hours in a day. A widely held unofficial interpretation is that the saffron stands for purity and spirituality, white for peace and truth, green for fertility and prosperity and the wheel for justice/righteousness.
