Years each of us spends as a pilgrim, as we see the yard of graves as far as our sight goes in distance, we acknowledge the death in various colors through assorted histories of humankind, across diverse cultures. The nature teaches us that death is part of world's cycle, like how plants that grow from soil must someday wither according to the changes of life.
Life of creatures must be lived as long as it has not yet reached its endpoint. No matter how harsh or cruel can sometimes, or rather most of time, life becomes, we must keep going, we must endure it. Some of us might be saved by delusion we apply on ourselves, pretentious jubilance by mortal possession. Some others, when successfully attain the knowledge of awakening, understand that life is factually full of misery.
