Promise to unity or understandability

We all swear to god and keep our promise till we die. But why to promise if the understated statement doesn't understood .Very great saying in ramayana that" let the angels come and demons die".it have different meaning in different rituals and when they promise that peoples call all the Vedas and make sure it serve.But those people know they could live happy until promise get broken so they arranged another 108 promise on the go so that they live better life and their family live the life of kings without suffering those people don't know Rama live for some 10~ -91 sand fall particles on the earth and those era people hold the handful of mud on precise  time and eat it and live life of god of Rama disciple and they still bears the fruits of solitude those era comes n gone those soul never apart.Those were only 108 last served by earth and waiting for Rama to come again,They grew and they become we.We should not became then.God gave brain to think subconscious to decide,think like child and do eldel-wise.Through age rituals language manipulated like"is it to neither nor if but to otherwise strong".those priest still serve the RITE and god only can provide them the Rite Script.
