Regulate the breath, be happy, link the mind with the Lord in your heart.
Let your speech be true and sweet.
Meditation results in marvels.
No one is wise by birth, for wisdom results from one own's efforts.
Where is the delusion when truth is known? Where is the disease when the mind is clear? Where is death when the Breath is controlled? Therefore surrender to Yoga.
In the practice of Yoga one can emphasize the body, the mind or the self and hence the effort can never be fruitless.
