"Zen strongly emphasizes freedom from all unnatural encumberances. Meditation is something artificially put on- it does not belong to the native activity of the mind. Upon what do the foul of the air meditate? Upon what do the fish in the water meditate? They fly and they swim... is not that enough? Who wants to fix his mind on the unity of God and man, or on the nothingness of this life? Who wants to be arrested in the daily manifestations of his life activity by such meditations as the goodness of a divine being, or the everlasting fire of hell?"
