Too much suffering is not good. If you become always manipulated by it, if suffering is always the boss, that is not good. And if you have too little suffering, you will not be inspired to pursue real happiness. That is why we speak of ‘precious human birth.’ Because being born in the human body provides just the right amount of suffering that we need in order to transform suffering into a source of wisdom and knowledge.
– Yongey Mingyur Rinpoche, “Trust Through Reason”
