DEATH IS CERTAIN

Death will definitely come, Life span cannot be increased, but decreases continuously. Death will come regardless of whether you have made time to practise Dharma. The Conclusion: Death is definite, therefore I must practise the Dharma.

THE TIME OF DEATH IS UNCERTAIN

The life span of beings in this world is not certain. There are more factors conducive to death than to life. Our bodies are very fragile. The Conclusion: The time of my death is uncertain; therefore practise Dharma immediately.

WHEN DEATH COMES ONLY DHARMA HELPS

Friends cannot help at the time of death.
Wealth cannot help at the time of death.
My body cannot help at the time of death.
The Conclusion: I must practise Dharma purely as only this can benefit at the time of death.
