The control of mind is the unique door to Freedom
Freedom is the result of the disenslavement of mind.
Who has conquered his own mind is a true potentate Maharaya (King).
The richest man is the one who has conquered his own desires, passions and mind.
If the mind is under control, it matters little whether you are in a palace or in a cave in the Himalayas, wether you dedicate yourself to intense worldly activity or remain silent.
The mind can be controlled by a tireless perseverance and a patience equal to that of who is devoted to empty the ocean, drop by drop, with a blade of grass.
To train a lion or a tiger is much easier than taming one's mind.
