The Divine Life Society was founded by the late Swami Sivananda Saraswati (1887 - 1963). Though unrelated to Swami Vivekananda who lived around the same time, both these modern era enlightened Hindu saints were among the forerunners of spreading universal Hindu education and promoting social welfare work as crucial spiritual missions.
Their website is a treasure trove of information on Hindu philosophy, spirituality and culture and has a lot of guides written by the Swami Sivananda and the current leaders of The Divine Life Society. Despite the 'bare-bones' simple looking format of this popular website, its wealth of information can keep you busy with knowledge and practices for a long time. It is a wonderful resource to be a part of the HinduSearchEngine.com. Translations of the site is also available in Spanish and German.
