In yogic culture Lord Shiva is not known as a God, but as the first Guru or the Adi Guru. He is the first Yogi. Out of his realisation, he became ecstatic and danced all over the mountains or sat absolutely still. He was constantly into bouts of stillness and bouts of dancing. All the gods who saw him, saw something was happening to him that they themselves did not know. When they finally got him to teach the method, Shiva expounded various types of yogas. The first part of Shiva's teaching was to Parvati. It was taught in a certain intimacy. In great detail, and in very gentle ways, Shiva expounded the ways of yoga to Devi. The second set of yogic teaching was expounded to the Sapta Rishis, or the first seven sages. When we use the word yoga, you should not think of twisting your body or holding your breath. We are talking about the very science of creation and how to take this piece of creation (you) to its ultimate possibility. We are looking at gaining mastery over the fundamental processes of life; the very process of creation and dissolution. It doesn't matter at what level of evolution a person is right now, for him also, there is a way. For every being on the planet, there is a certain way that is the advantage of yoga. ‪This teaching happened on the banks of Kanti Sarovar, near Kedarnath. Shiva is the Adi Guru, from whom yoga originated. In his teachings, Lord Shiva does not give any philosophical explanations, but instead gives very direct instructions on the methods to liberation. Siva Sutras and Vighyana Bhairava Tantra are popular texts that contain specific techniques to liberate the embodied soul from the limitations of the body and mind and experience his true blissful nature.
