大方廣圓覺修多羅了義經 1.25

1.25

"Kulaputra, all worlds' beginning and end, arising and ceasing, prior and posterior, existence and non-existence, gathering and dispersal, starting and stopping, thought succeeding thought, circulating and returning, their various graspings and rejections—all are saṃsāric transmigration. If one attempts to discern perfect enlightenment without having escaped transmigration, that nature of perfect enlightenment is made identical to cyclic flow; to avoid transmigration in this way is impossible. For instance, when one's eyes move, they can make still water seem agitated; again, when the eyes are fixed, a rotating fire-brand seems a circle. It is also like clouds scudding making the moon seem to move, or a boat traveling making the shore seem to shift. Kulaputra, while the spinning has not ceased, even those objects remaining stationary cannot be perceived as such; how much less can a mind defiled by saṃsāric transmigration, never having been purified, contemplate the Buddha's perfect enlightenment without itself spinning? It is for this reason that you have produced these three doubts.
