Mind precedes all knowables,
mind's their chief, mind-made are they.
If with a clear, and confident mind
one should speak and act
as one's shadow ne'er departing.

Happiness Follows The Doer of Good

Explanation: All that man experiences springs out of his thoughts. If his thoughts are good, the words and the deeds will also be good. The result of good thoughts , words and deeds will be happiness. This happiness will never leave the person whose thoughts are good. Happiness will always follow him like his shadow that never leaves him.
