Sivagiri is an area in Varkala Municipality of Thiruvananthapuram district in Kerala. It is a pilgrimage centre of Varkala Town where the tomb, or samadhi, of Sree Narayana Guru is situated. It is a place where Guru built the Sarada Temple dedicated to Sarada Devi. The tomb is an attraction for thousands of devotees every year, especially during the Sivagiri Pilgrimage days (Sivagiri Theerthadanam) from 30 December to 1 January. The Sivagiri Mutt, built in 1904, is atop the Sivagiri hill in Varkala Town. This is also the headquarters of the Sree Narayana Dharma Sangham, an organisation of his disciples and saints, established by the Guru to propagate his concept of "One Caste, One Religion, One God". The Guru Deva Jayanti, the birthday of the Guru, and the samadhi day are celebrated in August and September respectively every year. Colourful processions, debates and seminars, public meetings, cultural shows, community feasts, group wedding and rituals mark the celebrations. Guru's initial days at Sivagiri Gurudevan's association with Sivagiri in Varkala in south Kerala dates back to 1904. Varkala used to be known as the southern Benares. A lover of nature and places of natural beauty, Narayana Guru built a hermitage on top of the Sivagiri hill and stayed there, growing plants around it, and the once-solitary hill began to attract public attention. In due course of time, the Travancore state government granted the Sivagiri hill to Gurudevan and the people gave some of the surrounding places to him as gifts. Later Sivagiri grew into the nerve centre of Sree Narayana movements. At first, an elementary school was established there. A night school was also founded for the illiterate people of the untouchable castes. Many people came to Sivagiri to have a darshan of Gurudevan. Sarada Mutt After travelling to many places in South India and Sri Lanka and establishing temples, he did the prathishta of the spiritual figure Sree Sarada at Sivagiri in April 1912. It is the most remarkable one among his consecration of temple deities. The foundation for it was laid in 1909. The same year he composed the poem "Janani Navaratna Manjari". According to the Indian concept, the goddess Saraswati is the primary goddess of knowledge. But there are very few temples in Kerala with Saraswati prathishta. Sivagiri Sarada Mutt was planned and designed by Gurudevan who took a particular interest in it. Ordinary temples do not have windows.
