Pray
Pray is an introverted psychological act, done to pacify stress and excitement of the mind, by turning to abstract, non existing, never present, imaginary force, exogenous to the praying individual. Even if praying is done mostly within the group, it is act of submission of the individual to the authority, imaginary, or the one, who claims to represent the imaginary non existing, omnipotent, ever and everywhere present entity.
