“known as the five ‘hindrances’ (nīvaraṇa): sensual desire, ill-will, tiredness and sleepiness, excitement and depression, and doubt. An ancient simile compares the mind that is continually prey to the five hindrances to a bowl of water disturbed or contaminated in five ways: mixed with red dye, steaming hot, full of moss and leaves, ruffled by the wind, muddied and in a dark place.”
