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.)

    Make the most of your regrets; never smother your sorrow, but tend and cherish it till it come to have a separate and integral interest. To regret deeply is to live afresh.
    Henry David Thoreau (1817–1862)
