Death is a Teacher

Death is a silent yet eloquent teacher of truth. Death is a teacher that speaks openly and yet is not easily heard. Death is very much present in our modern world: and yet it has become an enigma to that world. Instead of understanding death, it would seem that our world simply multiplies it; death has become a quantity. The mystery of death, more terrible and sometimes more cruel than ever, remains incomprehensible to men who, though they know they must die, retain a grim and total attachment to individual life as if they could be physically indestructible.
 
Perhaps it is this failure to understand and to face the fact of death that helps cause so many wars and so much violence. As if men, attached to individual bodily life, thought they could protect themselves against death by inflicting it on others.
 
Death cannot be understood without compassion. Compassion teaches me that when my brother dies, I too die. Compassion teaches me that my brother and I are one. That if I love my brother, then my love benefits my own life as well, and if I hate my brother and seek to destroy him, I destroy myself also. The desire to kill is like the desire to attack another with a red hot iron: I have to pick up the hot metal and burn my own hand while burning the other. Hate itself is the seed of death in my own heart, while it seeks the death of the other. Love is the seed of life in my own heart when it seeks the good of the other.
