The iconography of Gautama Buddha in Laos and Thailand recall specific episodes during his travels and teachings that are familiar to the Buddhists according to an iconography with specific rules. The Buddha is always represented with certain physical attributes, and in specified dress and specified poses. Each pose, and particularly the position and gestures of the Buddha's hands, has a defined meaning which is familiar to Buddhists. In other Buddhist countries, different but related iconography is used, for example the mudras in Indian art. Certain ones of these are considered particularly auspicious for those born on particular days of the week.

A mudra is a symbolic or ritual gesture or pose in Hinduism, Jainism and Buddhism. While some mudras involve the entire body, most are performed with the hands and fingers.
