When Death Comes

In gita it says,u r not this body,u r eternal, so who dies? ego dies.what is ego? bharat,who thinks he is individual,if it is true,than a flower,an insect,an elephant they also r seperate,what r they made up of? five elements, so this 5 elements dissolve in itself,do we call it a death? there is not much difference between a good night sleep and death.the little difference is after a night sleep, we remeber our previous day,but after death, we change the old ,worn out instrument to a new one to fulfill the desires it died with,so we have to rejoice. but there is another higher way of dying, is to b just desireless, and you become eternal.ajar,amar,satchitanand.
