How should a person live life when freed from all the shackles of world,be it material,spiritual,religous ?

Only knows one 2 things what exist and that which made the universe to exist or multiverses or anything . What should be done by him/her .He knows godd/bad, crime,hate,fortune,unfortunate events,death,tragedy,luck don't matter. Health,wealth, children,wife,parents don't matter, Nothing matters. Total freedom even though its a relative term ?
