There is a story that when Shiva and Parvati entered into divine matrimony at Mount Kailash in the north, the place was unbalanced because of the multitude of holy beings witnessing the wedding. Lord Shiva asked Agastya Maharishi to proceed to southern India to balance the world. Agastya Maharishi then proceeded to Pothigai hills and balanced the world. Agastya Maharishi was able to visualise the wedding of Lord Shiva and Parvati on a Shivalingam that was at Tiru Kalyana Teertham at Pothigai hills. These hills are visited by several saints and sages from Himalayas particularly on a full moon day. The striking similarity between the profiles of Mt. Kailash and Agasthyamalai strengthen the mythological connections of these sacred peaks. While Swami Arulananda was at Pothigai hills, he often visited Subramania Swami temple in Tiruchendur. In 1981, on Thaipusam day (Full moon day in January), Agastya Maharishi appeared in Swamiji’s dream and asked him to proceed to Suruli Aandavar temple (Subramania Swami temple) at Suruli hills to practice Tapas. In this place, Subramania manifests as Suruli Aandavar. Suruli Velappar Temple in praise of Kartikeya is located near the falls. This temple is shaped like an OM Pranava. OM is the source mantra of the universal. This Mantra was generated before the Earth and all planets were created. At this cave one can hear the OM Mantra when you are in meditation frequency. This statement was told by Omgara guru Sidhar Gunaneethy, who is the founder of Rishi's Meditation. The Syed Sadai Masthan and Buhari Shaib Dargah at Suruli is an important worship place for Muslims. Syed Sadai Masthan cave is placed at opposite hills top side. Now, the forest Department is not given permission to worship there. Every April 14 Muslim people gather the Buhari Sahib Dhargah which placed at entrance of Suruli Falls. Both saints came to India to spread Islam in the Western Ghats area of Sivagiri and Suruli Falls. In November 2009, Minister of Environment and Forests, Jairam Ramesh, in a letter to Anil Kakodkar, Secretary, Department of Atomic Energy (India) (DAE) and Chairman, Atomic Energy Commission of India (AEC), denied permission for the Department of Atomic Energy to set up the India-based Neutrino Observatory (INO) project at Singara in Nilgiris, as it falls in the buffer zone of the Mudumalai Tiger Reserve (MTR).
