In yoga culture, Shiva is not only known as a "God", but as the first Guru or the Adi Guru. He is the First
Yogi that is Adi 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 mad dancing.
All the gods who saw him, saw something was happening to him that they themselves did not know.
Suddenly heaven felt like a bad place, because this guy is having such a good time! They felt, "We are missing out on something."
When they finally got him to teach the method, Shiva expounded various types of yogas depending upon the level of preparedness of
the person who was sitting in front of him.
The first part of Shiva's teaching was to Parvati, his wife. It was taught in a certain intimacy. In great detail, and in very gentle ways, Shiva expounded the ways of yoga to Devi. The yoga sutras of Shiva are such that almost in every sutra , he refers to her as the resplendent one, the gracious one, the beautiful one. So this teaching transpired between two people with utmost intimacy. Intimacy should not be understood as sexuality. It means there is no resistance; this person is absolutely open to whatever is being offered.
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 or anything like that we are not talking about a particular exercise or a technique. 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. This is when the world's first yoga programme happened.
