The simple explanation of a bend in a path or road is a change in spiritual direction, perhaps to accommodate new information. Whether the change is to the right or left may be important.
To bend as in bowing generally acknowledges a higher power or authority.
Psychological / emotional perspective: If you are bending forwards, this suggests submission or adapting to new circumstances, whereas bending backwards would signify a need to please or accommodate others.
Material aspects: When you are bending an object you are hoping to change – perhaps a project or way of life. When something is bent there is a distortion which needs to be understood.
To find yourself bending the rules shows an element of rebellion.
