Krishna says, “I am all-devouring death, I am death personified and I am immortality.” Therefore, anyone who comes face-to-face with death actually comes face-to-face with Krishna. Prabhupada also gives the example that when Dhruva Maharaja was entering into the flower airplane and death personified appeared before him, he simply stepped on the head of death personified and used it as a step for entering into the airplane. He did not see death as something fearful, but rather as a step to get to the place where he really wanted to go.
