There seems to be an attitude problem, as if we cannot shake ourselves out of a mindset of limited achievement.

Yoga is a vision for a harmonious future for humanity. It is an "stage" i.e. a state of mind not "system".

Culture of the mind must be subservient to the heart.

You can chain me, you can torture me, you can even destroy this body, but you will never imprison my mind.

Most folks are as happy as they make up their minds to be.

The cheerful mind perseveres and the strong mind hews its way through a thousand difficulties.
