At the age of twenty,Mahavira renounced his kingdom and family, gave up his worldly possessions, and spent twelve years as an ascetic. During these twelve years he spent most of his time meditating. He gave utmost regard to other living beings, including humans, animals and plants, and avoided harming them. He had given up all worldly possessions including his clothes, and lived an extremely austere life. He exhibited exemplary control over his senses while enduring the penance during these years. His courage and bravery earned him the name Mahavira. These were the golden years of his spiritual journey at the end of which he achieved arihant status.
