Successful Life
If at the time of death one can remember Krishna, one’s life is successful.
Srimad Bhagavatam 10.1.5-7,
Srila Prabhupada
Process of Birth and Death
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.
Remembering Krishna At The Time of Death
If one doesn’t practice remembering Krishna while one is struggling for existence, then it will not be possible for one to remember Krishna at the time of death.
Effect of Chanting
One need only chant the Hare Krishna mahamantra. Everyone engaged in the practice of chanting the Hare Krishna mahamantra will be completely cleansed, from the core of his heart, and be saved from the cycle of birth and death.
Srimad Bhagavatam 7.6.1,
Srila Prabhupada.
Death
The unsuspecting fish, who knew nothing but a life in the river, went about its routine like any other day, but in an instant was ripped out of its reality to meet with death.
Stopping The Repeated Cycles of Birth and Death
One who has taken his birth is sure to die, and after death one is sure to take birth again. Surrender to Holy names of the Lord & stop this cycle of repeated bithe & death.
