It may seem unrealistic to think we can ever become free from hatred, but Buddhists have systematic methods for gradually developing a tolerance powerful enough to give such freedom.
Compassion suits our physical condition, whereas anger, fear and distrust are harmful to our well-being. Therefore, just as we learn the importance of physical hygiene to physical health, to ensure healthy minds, we need to learn some kind of emotional hygiene.
A priest once quoted to me the Roman saying that a religion is dead when the priests laugh at each other across the altar. I always laugh at the altar, be it Christian, Hindu, or Buddhist, because real religion is the transformation of anxiety into laughter.

It is good to remember that the goal of Buddhism is to create Buddhas, not Buddhists, as the goal of Christianity is to create Christs, not Christians. In the same vein, my teachings are not meant to acquire followers or imitators, but to awaken beings to eternal truth and thus to awakened life and living.
Misunderstanding may arise by confusing the Buddhist and scientific definitions of death. Within the scientific system you spoke quite validly of the death of the brain and the death of heart. Different parts of the body can die separately. However, in the Buddhist system, the word death is not used in that way. You'd never speak of the death of a particular part of the body, but rather of the death of an entire person. When people say that a certain person died, we don't ask, "Well, which part died?"
Imagine a multidimensiona l spider's web in the early morning covered with dew drops. And every dew drop contains the reflection of all the other dew drops. And, in each reflected dew drop, the reflections of all the other dew drops in that reflection. And so ad infinitum. That is the Buddhist conception of the universe in an image.
The four catagories of existance, non-existance, both existance and non-existance, and neither existance nor non-existance, are spiderwebs among spiderwebs which can never take hold of the enormous bird of reality
Spend 5 minutes at the beginning of each day remembering we all want the same things (to be happy and be loved) and we are all connected to one another.
Love yourself and be awake- Today, tomorrow, always. First establish yourself in the way, Then teach others, And so defeat sorrow. To straighten the crooked You must first do a harder thing- Straighten yourself. You are your only master. Who else? Subdue yourself, And discover your master.
