What are the fixed gestures and sitting postures of Indian Kendra Buddha?

There are sitting statues and standing statues of Buddha in Kendra. There are fixed procedures for the gestures and sitting posture of Buddha statues. The posture of the Buddha standing in Gandhara is usually "fearless", that is, the blessing posture (the right arm is horizontally extended forward, the right palm is forward, and the five fingers are upward), and the posture of the Buddha sitting on the statue is "fearless" and "meditation posture", that is, meditation posture (the arms are drooping, the hands are folded up and down, and the palms are facing up, lying flat on the curved legs) or "turning the dharma wheel posture". In Indian art, sitting posture can also express some kind of spirit and emotion. Kendra's sitting posture is "lotus sitting", that is, according to the habit of Indian meditation, his feet are crossed, his feet are up, and he lies flat on his relatively curved thigh. The forms of these gestures and sitting postures were fixed by artists in Kendra, forming a basic procedure.
