Which symbols were used by Gandhiji in freedom struggle against British in India?

He made spinning on the Charkha and the daily use of khadi, or Coarse cloth made from homespun yam, very powerful symbols. These were not only symbols of self reliance but go of resistance to the use of British mill-made cloth.
He consciously rejected the well known clothes of the Indian ascetic and adopted the dress of the poorest Indian. Khndi, white or coarse, was to him a sign of purity, simplicity and of poverty. Weaning it became a symbol of nationalism.
