Good and learned friends, in method there is no distinction between sudden enlightenment and gradual enlightenment. Among men however, some are intelligent and others are stupid. Those who are deluded understand gradually, while the enlightened achieve understand understanding suddenly. But when they know their own minds, then they see their own nature, and there is no difference in their enlightenment. Without enlightenment, they remain forever bound in transmigration."
