Meditation results in marvels.
In the practice of Yoga one can emphasize the body, the mind or the self and hence the effort can never be fruitless.
Let your speech be true and sweet.
Regulate the breath, be happy, link the mind with the Lord in your heart.
Master your breath, let the self be in bliss, contemplate on the sublime within you.
No one is wise by birth, for wisdom results from one own's efforts.
