Yoga means to become flexible – not just physically but in every way. That means wherever you are, you are fine.  

The purpose of Yoga is to live strong. Strong not just in body but as a Strong Life.

To be in Yoga means to experience the oneness of existence.  

Changing your attitude is pretense - you cannot keep it up forever. The yogic system is about fundamental transformation - that is what ultimately counts.

This is the fundamental nature of Yoga and Mysticism: only if you become absolute Nonexistence, will you know Existence.
