Death

 Death is an inescapable and inevitable reality. To ignore it is utter foolishness. To avoid it is impossible. To hope for physical immortality is absurd.
 Make death a part of life by understanding that life without death is incomplete. As soon as we are born, we begin to die. Life is sacred and so we cannot afford to squander it in daydreams, fantasies, and false hopes. Life without death, pleasure without pain, light without darkness, and good without evil, are never possible. We must either accept both or rise above both, by overcoming embodiment through the Knowledge of the Self. Death is certain for all who are born. As the Bhagavad Gita says: "For to that which is born, death is certain, and to that which is dead, birth is certain. Therefore you should not grieve over the unavoidable."

Freedom comes when Desires end

"When all the desires that dwell in his heart are got rid of, then does the mortal [man] become immortal and attain Brahman in this very body."
