This is the line immediately preceding: William James said: "The deepest principle in human nature is the craving to be appreciated." Your passage means that the person who can satisfy the craving of another person to be appreciated will be a very loved person who everyone will hate to see die.

The undertaker makes money when you die because his job is to prepare your body for burial. If you have lived an exemplary life, even the undertaker will be sad to have this job. Hope that is helpful?

This is a quotation from the American writer Mark Twain: "Let us endeavor so to live so that when we come to die even the undertaker will be sorry."

Thank you so much for your advice. I will correct them next time. It's from a book: How to make friends and influence people. Here is the former paragraph: Lincoln once began a letter saying: "Everybody likes a compliment." William James said: "The deepest principle in human nature is the craving to be appreciated." He didn't speak, mind you, of the "wish" or the "desire" or the "longing" to be appreciated. He said the "craving" to be appreciated.

I'm glad you understand the paragraph, because I don't. It mentions "human hunger", then it mentions "heart hunger". Are we talking two different hungers here? What type of "hunger" are we talking about? Need more context. Is this a horror book? Are we talking about a serial killer? What does "hold in the palm of his hand" mean? Advice: "Thx" is not a word. "Plz" is not a word. "tellme" is two words. Use correct English when writing on this website. Don't be lazy and sloppy. It gives people a bad impression of you.
