If we have developed proper attitude, if we have cleansed or purified our heart, if we have considerably detached ourselves from material attachments and detached ourselves from the propensity for sense gratification and if we have considerably maintained or advanced ourselves in spiritual lives, then at the time of death we will pass the exam, just like a good student who has prepared through out the year will pass the exam with flying colours. But a student who has gone to school but who doesn't study properly, what happens to him?

Bhaktivinoda Thakura is saying, at the final moment he will be completely bewildered about how to face it as he didn't prepare himself.

This Krsna Consciousness movement is meant to prepare ourselves for that final moment.
