Sivaya Subramuniyaswami (born Robert Hansen; January 5, 1927 – November 12, 2001) was an American Hindu religious leader known as Gurudeva by his followers. Subramuniyaswami was born in Oakland, California and adopted Hinduism as a young man. He was the 162nd head of the self claimed Nandinatha Sampradaya's Kailasa Parampara and Guru at Kauai's Hindu Monastery which is a 382-acre (155 ha) temple-monastery complex on Hawaii's Garden Island.In 1947, at the age of 20, he journeyed to India and Sri Lanka and in 1949, was initiated into sannyasa by the renowned siddha yogi and worshiper of Lord Shiva, Jnanaguru Yogaswami of Jaffna, Sri Lanka who was regarded as one of the 20th century's remarkable mystics. In the 1970s he established a Hindu monastery in Kauai, Hawaii and founded the magazine Hinduism Today. In 1985, he created the festival of Pancha Ganapati as a Hindu alternative to December holidays like Christmas. He was one of Shaivism's Gurus, the founder and leader of the Saiva Siddhanta Church. He is part of the guru lineage of the Sri Lankan Alaveddy Hindus. His various institutions form a Jaffna-Tamil-based organization which has branched out from his Sri Subramuniya Ashram in Alaveddy to meet the needs of the growing Hindu diaspora of this century. He also established a seven-acre (2.8 ha) monastery in Mauritius, which includes a public Spiritual Park called "Spiritual Park- Pointe de Lascars". He oversaw more than 50 independent temples worldwide.His influence reflected the reach of his publications, including the approximately 30 books he wrote. Subramuniyaswami was described by Klaus Klostermaier as "the single-most advocate of Hinduism outside India". The book Religious Leaders of America explained Subramuniyaswami's role as "a pillar of orthodox Hinduism." Source: Wikipedia (en)
