A small prayer is a type of prayer that is short and concise. It is often used in religious ceremonies or as a way to express gratitude. The term 'small prayer' can also be used to refer to the insect known as a mantis, which is a six-letter word. The mantis is an insect that is known for its praying posture, where it holds its front legs together in a prayer-like position. This posture is thought to be a way for the mantis to ward off predators.
