Unless you see your nature, all this talk about cause & effect is nonsense. Buddhas don't practice nonsense.

All the suffering and joy we experience depend on conditions.

Our nature is the mind. And the mind is our nature.

But people of the deepest understanding look within, distracted by nothing. Since a clear mind is the Buddha, they attain the understanding of a Buddha without using the mind.

The awareness of mortals falls short. As long as they're attached to appearances, they're unaware that their minds are empty. And by mistakenly clinging to the appearance of things they lose the Way.

Whoever knows that the mind is a fiction and devoid of anything real knows that his own mind neither exists nor doesn't exist.

I do not need any writing, since I transmit teaching beyond words and ideas.
