ABOUT BUDDHISM

Through this we will come to experience lasting peace and happiness. These methods work for anyone, in any country, in any age. Once we have gained experience of them for ourselves we can pass them on to others so they too can enjoy the same benefits. Since some background knowledge of rebirth and karma is useful for understanding Buddhism, there now follows a brief introduction to these topics taken from Geshe Kelsang's book, Eight Steps to Happiness:
the Buddhist view of the mind
The mind is neither physical, nor a by-product of purely physical processes, but a formless continuum that is a separate entity from the body. When the body disintegrates at death, the mind does not cease. Although our superficial conscious mind ceases, it does so by dissolving into a deeper level of consciousness, call 'the very subtle mind'. The continuum of our very subtle mind has no beginning and no end, and it is this mind which, when completely purified, transforms into the omniscient mind of a Buddha.
actions and their effects
Every action we perform leaves an imprint, or potential, on our very subtle mind, and each karmic potential eventually gives rise to its own effect.
Our mind is like a field, and performing actions is like sowing seeds in that field. Positive or virtuous actions sow the seeds of future happiness, and negative or non-virtuous actions sow the seeds of future suffering. This definite relationship between actons and their effects - virtue causing happiness and non-virtue causing suffering - is know as the 'law of karma'. An understanding of the law of karma is the basis of Buddhist morality.
what happens when we die?

samsara - our experience of the world
This uninterrupted cycle of death and rebirth without choice is called 'cyclic existence', or 'samsara' in Sanskrit. Samsara is like a Ferris wheel, sometimes taking us up into the three fortunate realms, sometimes down into the three lower realms. The driving force of the wheel of samsara is our contaminated actions motivated by delusions, and the hub of the wheel is self-grasping ignorance, which is a mistaken mind that holds phenomenon to be inherently existent and that gives rise to all other delusions. For as long as we remain on this wheel we shall experience an unceasing cycle of suffering and dissatisfaction, and we shall have no opportunity to experience pure, lasting happiness.
Enlightenment, or Nirvana
By practising the Buddhist path to liberation and enlightenment, however, we can destroy self-grasping, thereby liberating ourself from the cycle of uncontrolled rebirth and attaining a state of perfect peace and freedom. We shall then be in a position to help others to do the same.
A more detailed explanation of rebirth and karma can be found in the books Introduction to Buddhism and Joyful Path of Good Fortune.
