A good teacher is like a candle - it consumes itself to light the way for others.

The saying likens teaching to a candle’s flame: it gives light to others by steadily expending its own substance. Read this way, the “good teacher” is defined by self-giving—time, energy, patience, and often personal sacrifice—so that students can see further than they otherwise could. The metaphor also implies a moral dimension to education: knowledge is not hoarded but transmitted, and the teacher’s value lies in enabling others’ growth. At the same time, the image can be taken as both praise and warning: society benefits from teachers’ devotion, but the work can be consumptive if support and recognition are lacking.
