What is the sutta that uses the following metaphor?
Firefly(Samsaric being) jumps into candlelight seeking a pleasure(Tanha), not knowing(Avijja) that the candlelight will burn the firefly to death(Samsaric Dukkha).
“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.”
