"In the yogic culture, Shiva is not known as a god, but as the Adiyogi or the first yogi – the originator of
yoga. He was the one who first put this seed into the human mind. According to the yogic lore, over fifteen thousand years ago, Shiva attained to his full enlightenment and abandoned himself in an intense ecstatic dance upon the Himalayas. "
His first disciples were "seven celebrated sages who are today known as the Saptarishis, and are worshipped and admired in Indian culture. Shiva put different aspects of yoga into each of these seven people, and these aspects became the seven basic
forms of yoga.
The Saptarishis were sent in seven different directions to different parts of the world to carry this dimension with which a human being can evolve beyond his present limitations and compulsions. They became the limbs of Shiva, taking the knowing and technology of how a human being can exist here as the Creator himself, to the world.
Whatever dimension of existence you are in right now, you can go beyond that – there is another way to live. He said, "You can evolve beyond your present limitations if you do the necessary work upon yourself." That is the significance of the Adiyogi." (Sadhguru "Adiyogi —the First Yogi")
