Famous quotes containing the words path and/or integral:

    Whoever heeds instruction is on the path to life, but one who rejects a rebuke goes astray.
    Bible: Hebrew, Proverbs 10:17.

    Self-centeredness is a natural outgrowth of one of the toddler’s major concerns: What is me and what is mine...? This is why most toddlers are incapable of sharing ... to a toddler, what’s his is what he can get his hands on.... When something is taken away from him, he feels as though a piece of him—an integral piece—is being torn from him.
    Lawrence Balter (20th century)
