In no way can it be uttered, as can other things, which one can learn. Rather, from out of a full, co-existential dwelling with the thing itself - as when a spark, leaping from the fire, flares into light - so it happens, suddenly, in the soul, there to grow, alone with itself.

Martin HeideggerSpiritual superiority [consists in] deep dedication ... in the form of the most rigorous training, as commitment, resistance, solitude, and love.
Martin HeideggerTeaching is more difficult than learning because what teaching calls for is this: to let learn. The real teacher, in fact, lets nothing else be learned than learning. His conduct, therefore, often produces the impression that we properly learn nothing from him, if by "learning" we now suddenly understand merely the procurement of useful information.
