You are driving car, running with seventy miles speed.. it is smashed accidently. But you are alive then you have to change your car. Similarly, we can drive this machine called the body for so many years; then it becomes old and we have to change it for another machine. This is the process of birth and death.
Every person who has taken birth in this material world is destined to meet death, which is simply a matter of changing bodies, but no one except the Krishna conscious person knows where he will be going after this change of bodies.
The kitten is feeling pleasure: “Oh, my mother is carrying me.”
The deer is feeling death: “Oh, now I’m going to die.”
So, although both devotees and nondevotees die, there is a diffrence of feeling at the time of death.
Death is not a big thing, what is important is God’s service.
