To perceive that form reveals the void, and to see that the void reveals form, is the secret for the overcoming of death. To the extent that one is unaware of space, one is unaware of one's own eternity — it's the same thing!
We do not know whether it is good to live or to die. Therefore, we should not take delight in living, nor should we tremble at the thought of death. We should be equiminded towards death. This is the ideal. It may be long before we reach it, and only a few of us can attain it. Even then, we must keep it constantly in view, and the more difficult it seems of attainment, the greater should be the effort we put forth.
Ageing destroys youth, sickness destroys health, degeneration of life destroys all excellent qualities and death destroys life. Even if you are a great runner, you cannot run away from death. you cannot stop death with your wealth, through your magic performances or recitation of mantras or even medicines. Therefore, it is wise to prepare for your death.
It is an exquisite and beautiful thing in our nature, that, when the heart is touched and softened by some tranquil happiness or affectionate feeling, the memory of the dead comes over it most powerfully and irresistibly. It would seem almost as though our better thoughts and sympathies were charms, in virtue of which the soul is enabled to hold some vague and mysterious intercourse with the spirits of those whom we loved in life. Alas! how often and how long may these patient angels hover around us, watching for the spell which is so soon forgotten!
From a Buddhist point of view, the actual experience of death is very important. Although how or where we will be reborn is generally dependent on karmic forces, our state of mind at the time of death can influence the quality of our next rebirth. So at the moment of death, in spite of the great variety of karmas we have accumulated, if we make a special effort to generate a virtuous state of mind, we may strengthen and activate a virtuous karma, and so bring about a happy rebirth.
