There is an old illusion. It is called good and evil.

The Grand Illusion, one of the great war films of all time.

The communist world, it may be noted, has one big myth (which we call an illusion, in the vain hope that our superior judgment will make it disappear). It is the time-hallowed archetypal dream of Golden Age (or Paradise) where everything is provided in abundance for everyone, and a great, just and wise chief rules over the human kindergarten. This powerful archetype in its infantile form has gripped them, but it will never disappear from the world at the mere sight of our superior points of view. We even support it by our own childishness, for our Western civilization is in the grip of the same mythology. Unconsciously, we cherish the same prejudices, hopes, and expectations. We too believe in the welfare state, in universal peace, in the equality of man, in his eternal human rights, in justice, truth, and (do not say it too loudly) in the Kingdom of God on Earth.
The sad truth is that man's real life consists of a complex and inexorable opposites - day and night, birth and death, happiness and misery, good and evil. We are not even sure that one will prevail against the other, that good will overcome evil, or joy defeat pain. Life is a battleground. It always has been, and always will be; and if it were not so, existence would come to an end.

Thus in a single phrase I can define the great illusion concerning 'love' in this world. It is the effort to join reality with the apparition.

What a strange illusion it is to suppose that beauty is goodness.

Such vastness makes for illusion, a kind of illusion that comprehends reality, and where it exists there is always wonder and exhilaration.

The great cosmic illusion is a hierophany.... One is devoured by Time, not because one lives in Time, but because one believes in its reality, and therefore forgets or despises eternity.

The End of History Illusion is what psychologists call the tendency for people to be keenly aware of how much they’ve changed in the past, but to underestimate how much their personalities, desires, and goals are likely to change in the future.

Illusions commend themselves to us because they save us pain and allow us to enjoy pleasure instead. We must therefore accept it without complaint when they sometimes collide with a bit of reality against which they are dashed to pieces.

We're hallucinating. And that's what this world is: a mass hallucination, where fear seems more real than love. Fear is an illusion. Our craziness, paranoia, anxiety and trauma are literally all imagined.

Since everything is only an illusion, perfect in being what it is, having nothing to do with good or bad, acceptance or rejection, one might as well burst out laughing! – Longchenpa

Life presents itself as a continual deception, in small matters as well as in great. If it has promised, it does not keep its word, unless to show how little desirable the desired object was; hence we are deluded now by hope, now by what was hoped for. If it has given, it did so in order to take. The enchantment of distance shows us paradises that vanish like optical illusions, when we have allowed ourselves to be fooled by them. Accordingly, happiness lies always in the future, or else in the past, and the present may be compared to a small dark cloud driven by the wind over the sunny plain; in front of and behind the cloud everything is bright, only it itself always casts a shadow. Consequently, the present is always inadequate, but the future is uncertain, and the past irrecoverable.

The illusion that one has understood the past feeds the further illusion that one can predict and control the future. These illusions are comforting. They reduce the anxiety that we would experience if we allowed ourselves to fully acknowledge the uncertainties of existence.

Illusion is the first of all pleasures
