Sadhu - In Hinduism, sadhu is a common term for an ascetic or practitioner of yoga (yogi) who has given up pursuit of the first three Hindu goals of life: kama (enjoyment), artha (practical objectives) and even dharma (duty). The sadhu is solely dedicated to achieving moksha (liberation) through meditation and contemplation of God. Sadhus often wear ochre-colored clothing, symbolizing renunciation. 'Sadhu!' is also a Sanskrit term used as an exclamation for something novel.
