You say: “He lost his life” or “my life”, as if life were something that you can possess or lose. The truth is: you don’t have a life, you are life. The One Life, the one consciousness that pervades the entire universe and takes temporary form to experience itself as a stone or blade of grass, as an animal, a person, a star or a galaxy.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
Words can confer strength; they can drain it off; Words can gain friends; they can turn them into enemies; words can elevate or lower the individual. One must learn the habit of making one’s words sweet, soft, and pleasant.
As long as you have attachment to the body and attachment to objects, fear and suffering will be with you. Therefore Krishna told Arjuna to develop his discrimination and rid himself of body consciousness. Only then he would be able to develop integral vision.
