Ud 6.9  - Adhipataka Sutta: Like Moths to the Flame
translated from the Pali by Andrew Olendzki


  “The insects are drawn irresistibly in the dark night to the shining
  lamps, but in their zeal to approach the light they go too far and
  only meet their doom. Humans likewise are drawn to the pleasures of
  the senses, to what is seen and heard, not realizing the dangers
  involved. When we get too close — when we hold on with too much
  attachment — we get burned by suffering. The senses can still be
  enjoyed, as the moth can stay circling the flame, but only when one
  holds the proper distance. This quality of "stepping back" or
  "standing off" from obsession with the senses is something that is
  cultivated with the practice of mindfulness meditation.”
