Swami Sivananda: Do not brood
Do not brood over your past mistakes and failures as this will only fill your mind with grief, regret and depression.
Do not repeat them in the future.
Siv?nanda Saraswati (September 8, 1887 - July 14, 1963) was a Hindu spiritual teacher and a proponent of Yoga and Vedanta. Siv?nanda was born Kuppuswami in Pattamadai, in the Tirunelveli district of Tamil Nadu. He studied medicine and served in British Malaya as a physician for several years before taking up monasticism. He lived most part of his life near Muni Ki Reti, Rishikesh.
He was the founder of The Divine Life Society (1936), Yoga-Vedanta Forest Academy (1948) and author of over 200 books on yoga, Vedanta and a variety of subjects. He established Sivananda Ashram, the headquarters of The Divine Life Society (DLS), on the bank of the Ganges at Sivanandanagar, at a distance of 3 kilometres from Rishikesh.
Sivananda Yoga, the yoga form propagated by his disciple Swami Vishnudevananda, is now spread in many parts of the world through Sivananda Yoga Vedanta Centres. These centres are not affiliated with Sivananda's ashrams, which are run by the Divine Life Society.
