Prostration and attachment to rites and rituals Why isn't prostration considered as a rite or a ritual in the sense of silabbata paramasa (one of the fetters that had to be abandoned to become a stream-enterer)?

I wonder how this practice can contribute to insight especially when prostration is done mechanically (as practiced around Buddhist pagodas in Birma; Sri Lanka and Thailand)?
Preforming a ceremonial act isn't the same thing as clinging to rites and rituals. Clinging to rites and rituals specifically means that you think that some ceremonial action has some sort of power in it that can take you to enlightenment.
