Most religions put a great deal of emphasis on moral behavior as if they are really saying, “This pleases God and if you please God enough times you’ll get a reward for it; he may even protect you from harm.”
When we turn to Buddhism we find that there is no God to please. If there is such a thing as Buddhist morality it is how one handles a subtle world illusion of great depth, or if your prefer, a spectacular dream, so as to not get trapped in it again and again by rebirth.
This world illusion is ultimately devoid of reality. No matter how many times we passionately engage with the illusion it will never be anymore than empty and hollow; ultimately unfulfilling. We can crave its objects; we can crave our own psychophysical bodies and the particular world they inhabit and a particular time. This does not make the power of the illusion any less, rather the opposite is true, such behavior makes the illusion seem more concrete than it is. According to the Bhavasankrânti Sutra:
"When at the end of life the mental consciousness (manovijñâna) is about to disappear, all the actions that have been [previously] preformed, appear in front just as the image of the beautiful female that has been seen in dream appears before the man when he remembers after awaking from sleep. Thus, O king, when the consciousness has disappeared and the future consciousness is born, it (or he) is born either amongst men, or gods, or beasts or ghosts or in hell."
All this is a dynamic process consisting of countless actions and fruits of actions, or again-births which, taken together, resemble the flow of a stream of water. There is a flow of continuing differences but as the selfsame universal substance (which is pure Mind). It is also the great wheel of samsara.
This is where Buddhism’s morality comes into play. We can either try for lots of good merit doing good deeds (karma), hoping for a better dream, or we can decide to transcend the whole thing which is much more difficult, requiring a much different morality which involves mystically seeing the substance from which our dreams are spun (it’s pure Mind).
