धूमेनाव्रियते वह्निर्यथादर्शो मलेन च। यथोल्बेनावृतो गर्भस्तथा तेनेदमावृतम्॥

Translation
As fire is covered by smoke, as a mirror by dust, and as an embryo by the womb, so is knowledge covered by desire.
Commentary
Three powerful analogies for how desire obscures wisdom - smoke covering fire (easily cleared), dust on a mirror (needs effort), and a womb covering an embryo (deeply embedded). Different levels of desire require different levels of effort to remove.
