We cant find the contiuety in the happiness ...one is happy while doing sex ..when edaculates ..happiness ends ..one on drug ..etc
Some are happy when they blew themselves up in bomb blast and killing others..
but the real happiness lies within ..which is everlasting because self does not die with time..
find yourself why are you here on earth ? this is not just the chance ..if you can see there is much more ..when you find the gate you will be happy not till death but after death...
