Hands can have a number of different potential meanings. They are the portion of our body associated with the ability grasp and hold things and could represent the idea of grasping an idea in some cases. The positioning and posture of the hand can have a significant impact upon its meaning. For example two hands reaching for one another as shown in the photo speaks of relationship or greeting. A hand help up, palm outward would indicate "stop", while the same hand lifted above the head might mean praise and a hand held out palm up could be a request or the need to receive something.
