Why from within ? The truly 'from within'.. and not from the surface of ego or skin or whatever... must inspire to live the purpose.
How many of the people you know live 'inspired' life ? !.. Really an inspired life... ! May be 'inspired' is a momentary thing ? Is it ? Then everyone has one or the other 'inspired' moment.. isn't it ? Was Gandhi inspired...driven..passionate all his life ? or was it only few moments... or was he 'ignited' so much...in those few moments to live an inspired life ?...Ok what about the great Buddha ? Once ignited did he live really an inspired life ? Tall examples... of course the idea is 'aim for the sun.. at least reach terrace of the empire state building..'
If it is mundane.. its not in sync with the purpose ..and if it is not in sync with purpose its wasteful... nothing 'inspired' about wasteful !
