There cannot be a cause without an effect, the present must have had its cause in the past and will have its effect in the future.
The effect is delusion, and therefore the cause must be delusion.
Something cannot be made out of nothing. Nor can something be made to go back to nothing.
Nothing can be produced without a cause, and the effect is but the cause reproduced.
No effect of work can be eternal.
Everything has a cause.
As the cause is, so the effect will be.
