A discussion of nature is given.Time is discussed with respect to certain other factors of nature.A potential energy equation is given which holds all relevant information about any system at equilibrium or non-equilibrium state with no restriction on number of phases.A differential form of the fundamental equation is also given,and it gives the amount of energy released if one or more of the variables are changed.The states of different distances in coupled verses are derived.There is no system of measurements outside the human mind,every verse calculates dynamically for itself.Vessel design using sub-verses and gates is discussed.The fundamental equation has important application for human self-development(martial arts).
