The Sanskrit term Saucha derives from ancient Indian books and can be literally translated as purity, cleanliness and clearness. Saucha is part of one of the five Niyamas in Yoga - the principles of yoga philosophy - and covers the cleanliness of the body and the earth, as well as the purity of mind. This Niyama reminds one to live a healthy and sustainable life, while keeping the body and mind pure. Healthy diet, personal hygiene and self0care are all considered Saucha; and is therefor essential for happiness and general well-being.
