27. Do not give way to heedlessness. Do not indulge in sensual pleasures. Only the heedful and meditative attain great happiness.
28. Just as one upon the summit of a mountain beholds the groundlings, even so when the wise man casts away heedlessness by heedfulness and ascends the high tower of wisdom, this sorrowless sage beholds the sorrowing and foolish multitude.
– Dhammapada II – Appamadavagga: Heedfulness 27 – 28
