The Laughing Buddha, or Hotei, is a classic Chinese image. We don't know what the historical Buddha looked like, but, as a yogi, he almost certainly wasn't fat. But in popular Chinese culture, a fat, laughing man is a sign of happiness and success, and, therefore, of good fortune.
The real gifts of the Buddha are not material, but are grounded in an Awakening that gives us the feeling of unconditional peace and easy joy in all circumstances. A Buddhist practitioner, after Awakening, returns to the world to share peace and joy. This came to be symbolized by a fat, happy merchant bringing gifts into town from the wilderness, where he used to meditate, and his name is Hotei.
Remember that Enlightenment - and success in life - are both the result of hard work. Keep a Hotei (or more than one) near you, especially at your desk, to remind yourself to keep laughing, keep working, and keep returning to joy and work until you succeed.
Where should you put your laughing Buddha? Trust your own feeling about that - that is much more important than someone's ideas of the right corners and directions! Hah!
