Let the wise one control his thoughts, for they are difficult to perceive, often elusive, and they rush about frantically: a mind well controlled achieves peace and happiness.
How does one stay mindful? Where feelings are known as they arise, known as they persist, known as they pass away. Thoughts are known as they arise, known as they persist, known as they pass away. Perceptions are known they arise, known as they persist, known as they pass away. This is how a monk stays awake.
I reached in experience the nirvana which is unborn, unrivalled, secure from attachment, undecaying and unstained. This condition is indeed reached by me which is deep, difficult to see, difficult to understand, tranquil, excellent, beyond the reach of mere logic, subtle, and to be realized only by the wise.
Thus all things are subject to death, sorrow and suffering. I became aware that I too was of the same nature, the nature of beginning and end. What if I searched for that which underlies all creation, that which is nirvana, the perfect freedom from unconditioned existence?
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.
Within the framework of the Buddhist Path, reflecting on suffering has tremendous importance because -realizing the nature of suffering, you will develop greater resolve to put an end to the causes of suffering and the unwholesome deeds which lead to suffering. And it will increase your enthusiasm for engaging in the wholesome actions and deeds which lead to happiness and joy.
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?"
In today’s interconnected and globalized world, it is now commonplace for people of dissimilar world views, faiths and races to live side by side. It is a matter of great urgency, therefore, that we find ways to cooperate with one another in a spirit of mutual acceptance and respect.
If there is no other world and there is no fruit and ripening of actions well done or ill done, then here and now in this life I shall be free from hostility, affliction, and anxiety, and I shall live happily.
Therefore, do not eat meat which will cause terror among people, because it hinders the truth of emancipation; not to eat meat? this is the mark of the wise.
