Everything outside of the scope of the Shiva soul is Shakti: our mind and body and all that can be perceived by the senses at any moment. This is the eternal other. Many of us would like to change this. We think we are the body and have control over our body and mind and seek to make changes here, but the truth is that we are all fools. This coming together of soul (Shiva), body and mind (Shakti) is the divine play that we are advised to approach as a witness. This is the field of karma; the interplay between subject and object. We have no freedom here.
