Sadhus are ascetic practitioners in Hinduism who dedicate their lives to spiritual pursuits. They often renounce worldly possessions and live a life of simplicity, focusing on meditation, prayer, and self-discipline. Sadhus can be found in various sects and traditions, each with its own practices and beliefs. Many sadhus wear distinctive clothing, such as orange or saffron robes, symbolizing their renunciation of material life. They may also adorn themselves with ash, beads, or other symbols of their faith. Sadhus often gather at religious festivals, such as the Kumbh Mela, where they share their teachings and experiences with others.
