sath

that which is permanent is called sath. our shasthras say that  while we see so many things in the universe, actually it is jadam[inert]. so whenever we prepare our bio-data- firstly we give our name. secondly age, qualifications, experience, e.t.c. but really speaking none of these are permanent. even people change their names, age also increases even after ur biodatas are given as u do'nt get jobs immediately.u may be adding qualifications, experience change with no of years, so none of them is permanent. hence we update the biodatas very often, but one thing does not change, that i does not change. as everything revolves round ur own self. this i from ur childhood to ur old age remains the same. it does not age, it is beyond time and space. hence it,s immortal. self does not have change. it  is ever permanent. therefore it's satyam. it is present in all  times ie yesterday ,today and tomorrow. we search for those happiness based upon what we see in the world. that's why we are unhappy to get real happiness. if u inquire into ur self u wll attain permanent happiness ie  called Ananda. but ananda cannot be obtained without awareness, ie chit.we shall about this later.
