Whoever knows that the mind is a fiction and devoid of anything real knows that his own mind neither exists nor doesn't exist.
Without the mind there is no Buddha. Without the Buddha there's no mind.
If your mind is pure, all buddha-lands are pure.
Life and death are important. Don't suffer them in vain.
Buddhas don't practice nonsense.
Buddhas move freely through birth and death, appearing and disappearing at will.
