Elightenment is typically found by weakening the ego, the self. Monks learned long ago that all suffering originates from within. They practice non reaction, simply observing the world around them, floating dettached in their minds. They would rather be a rock than a person. Depression colours everything. Its a reaction to life, or to the self. Ironically, true elightenment would require being like a rock, unable to react cognitively to anything. To simply be, to experience without reaction or judgement.
