Krishna says...

[righthanded]

Thinking about sense -objects
Will attach you to sense-objects;
Grow attached, and you become addicted;
Thwart your addiction, it turns to anger;
Be angry, and you confuse your mind;
Confuse your mind, you forget the lesson of experience;
Forget the lesson of experience, you lose discrimination;
Lose discrimination, and you miss life's only purpose.

-Bhagavad-Gita
