What can one really say??

Well today, I was having some choco-nut gelato and just contemplating on why people still use plastic and what is one really supposed to DO when it is thrust into one's hands or one cant help but use it..Anyway, it suddenly hit me that maybe the purpose of life is to find the purpose of life...?? What else can it be?? And the other side says just shut up and go on with your seva, sadhana and satsang...But it just comes and with time most of the answers do too, somehow....And i figured, all I sometimes really want to do is seva- even as a profession...and be there doing it all my life...at the feet of my Guru- that s the most important part..
