A devotee knows that even at his death Krishna will protect him. The real test of our devotion will be at that time.
Death is not a big thing, what is important is God's service.
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.
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.
