Famous quotes containing the words path and/or integral:

    “She’s in the house.
    She’s at turn after turn.
    She’s behind me.
    She’s in front of me.
    She’s in my bed.
    She’s on path after path,
    and I’m weak from want of her.
    O heart,
    there is no reality for me
    other than she she
    she she she she
    in the whole of the reeling world.
    And philosophers talk about Oneness.”
    —Amaru (c. seventh century A.D.)

    “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)
