Although you will find Happy Buddhas on nearly any Feng Shui related site, what you won"t find is a standard meaning for each of the Buddhas. Some sites refer to them generically as being for prosperity and abundance; other sites attribute them to specific uses, but the meanings are inconsistent from site to site. We have found the following to be the most popular interpretation with the alternate interpretation in parentheses given with the description of the Buddha.
Safe Travels (Adventurous): Stick w/bag over shoulder, holding wealth ball
Abundance (Prosperity): Hands raised above head, holding Ru-Yi pot (bowl of plenty)
Spiritual Journey (Longevity): Gourd of enlightenment hanging from stick, fan in one hand, necklace of beads
Long Life (Happiness): Seated on bag of blessings, one hand raised holding wealth ball, Ru-Yi pot in other hand
Love (Enlightened): Seated w/feet together, holding wealth ball, bag over shoulder
Happy Home (Tranquility): Seated w/parasol behind back
Perhaps the best way to determine what each Buddha signifies for you is to understand the meaning of each of his symbols. It will also help you to identify Happy Buddhas that are similar to but not exactly like those shown (and described) in this article.
The Ru-Yi is known as the bowl of plenty (it is also the shape of Chinese ingots) and signifies plenty, abundance, and wealth.
The bag is said to be filled with blessings (including children) that the Happy Buddha distributes freely.
The parasol deflects misfortune, thereby offering protection.
The Buddha waves the fan to banish troubles and misfortune.
The Wu-Lou (gourd) is a symbol of longevity and good health.
The wealth ball is sometimes seen as a pearl. In China, the pearl represents immortality, potentiality, and wisdom. Treasure dragons were believed to live in caves deep in the earth and to possess a magical pearl that multiplied if it was touched. This pearl was a symbol of the most valuable treasure, wisdom.
The necklace of beads is the mala, the Buddhist string of prayer beads.
