Teachings from our holy books
Everyone in this world works by its nature but what if when someone follows reverse of its nature for example a girl develops a habit of strong man and a boy developed a caring habit in case of girl she started taking responsibilities and living as strong independent life and she became strong and she became busiest person in the world in this life her face may look like man too… On the other hand boy who being more busy in household works and care like a females may develop habit of female. During next birth they may change to opposite gender… And in next life a boy who became girl can marry and a girl that developed habit of men may become successful business man and rich but even thou they gets no satisfaction an net of desires may go on therefore Buddha told in this world nothing remain same
