I have been a practitioner and researcher of Sivayogas of the eighteen immortal siddhas for the past forty-three years. The term Siddha is used widely in Indian religions and culture. Siddhas are perfected masters who have reached a high degree of physical as well as spiritual perfection or enlightenment.
When compared to the vedantic yogas, the siddha yogas offer different types of yogas. Chandra yoga is one of the Siva yogas explained by Thirumoolar. Thirumantiram is a classic Saivaite work. Different kinds of yogas are explained in it. Kayakalpa yoga, Vasi yoga, Amuridharanai, Chandra yoga etc. These yogas are in the Siva agama texts, Thirumantiram is the abridgement of twenty-eight Siva agamas. The veeragama deals with different kinds of Sivayogas. I am making my humble efforts to present this yoga to the international community. Yama, Niyama, Asana, Prathyahara, Dharana in Chandra yoga.
