In yogic culture, there are two aspects to Shiva. The word ‘Shiva’ literally means ‘that which is not’. Everything that is has come from ‘that which is not’. If you look up at the sky, you will see many stars and celestial objects, but still the biggest presence out there is a vast emptiness. It is in the lap of this No-thingness that the dance of creation is happening right now. This emptiness, which is the very basis of creation, is referred to as ‘Shiva’.
Another dimension of Shiva is Adiyogi, the first yogi, who opened up the incredible science of yoga for humanity. Yogic culture moves seamlessly from invoking Shiva as the basis of creation to invoking Shiva as the first yogi.
