Enlightenment for the common man

 What is Enlightenment from the point of view from a common man like me

I like all of us go by results,benefits and the feelings of well being before adopting any life changing pratices and new technologies in self development and health .what does enlightenment offer to me instantly or in the near future in measurable way ?  I had gone through the recorded version of few of our most celebrated and widely accepted on their experience of enlighttenment. They  had a sudden experience of oneness,oneness with all beings a total merger ,they lost count of time space and all limitation.they experience unalloyed joy which had no basis ,a  kind of unreasonable happiness.All our mundane happiness must have a solid reason to be happy such as getting and achieving .but the joy these enlightened few speak off is  of a different kind .Anyway it is ok .Then what .to a common man like me .we want to be happy always we hate to be unhappy .we hate to be stressful  to be sad . these enlightened few tell us that they are beyond sorrows and are always happy without any cause.,they warn ud ,though,life will be the same ,problems and pains will still be there,life will not be a bed of roses.But there will be shift in perception of suffering .Suffering loses it grip on us .the definition undergoes drastic change .suffering distanced itself from the list of synonym of sadness and limitation..Oh My God .I like this shift this unalloyed happness.Aurbindo beautifully define man as God who had firgotten that he is God .Then what am I to do achieve this .I pondered over this .Bhagavan Ramana says that there is nothing to be attained nowhere to reach as we are already perfect already complete .All tell is that we need not renounce or go to forests .where is the catch .Sadhguru Jaggi vasu dev,as I understand,  defines spiritual growth as our progress in becoming happy and happier .Becoming  more and more  self - less  is not only an act of charity but it is a royal highway to more and more happier and joyful life .Caring for others and service to others with compassion is the best and eadiesy  way to be happy and taste the glimmering of enlightenment.
