It has many components, the objects known and the means to know them.
They serve two roles.
When in strong association with the perceiver they produce pleasure or pain –
when this association is absent they let the perceiver visualise its own nature.
Experience of pleasure or pain is by the perceiver.
Freedom from them is also its fundamental situation.
This freedom is no different from Mukti.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 18
