Ball of happiness
The balls of Happiness are carved in the wood of a tree named Neem which means "which heals all diseases", because it has innumerable healing virtues.
This tree often grows in the center of temples in India because it is also claimed to have positive virtues of prosperity and fertility. It is for this reason that when the tree dies, it is used to create Balls of Happiness. They are a very strong symbol in Feng-Shui to strengthen the area of health, finance or love.
