Lotus
Krathong are often made in the shape of a lotus blossom, which symbolizes the flowering of the human spirit under Buddhism. As a symbol, the lotus was adopted from the Hindus by the Buddhists in India, who introduced it into their sculpture, painting, and literature. It is identified with purity and perfection because it grows out of the mud and yet is not defiled by it. In much the same way, humankind should be able to live in an evil and impure world without being influenced by it.
