Gandhiji was an ardent believer of Satyagraha as a powerful weapon. The word Satyagraha means truth-force. It embraces civil disobedience and a relentless pursuit for truth and peace. This inspirational concept, which completely changed the face of Indian struggle for independence, was first tested in South Africa. Gandhiji proposed certain rules for satyagrahis to follow. He trained the Indians during the South African passive resistance campaign. In short, this was a trial run for his future campaigns.
No worship of violence and belief in suffering the insults patiently etc. are the mottos of a satyagrahi. Satyagraha does not aim at humiliating rivals, but aims to soften their heart by peace. Satyagraha was fruitful in South Africa and along with this, Gandhiji practiced self-reliance. It was compulsory for him that his family should also be self-reliant. He used to wash his cloths by himself. He cut his own hair and that of his children as well.
In short, it is clear that the Indian freedom struggle was a much bigger test for Gandhiji and his idea of Satyagraha.
