The Vaisheshika system is one of the six orthodox schools of Hindu philosophy. It believes that all physical objects are composed of eternal, indivisible atoms that combine and separate. The system categorizes all objects of knowledge into seven "padarthas" or categories - substance, quality, motion, generality, particularity, inherence, and non-existence. It also believes in an omniscient, omnipotent God that directs the operation of atoms according to moral laws and karma.
