Everything good and bad comes from your own mind. To find something beyond the mind is impossible.

The ignorant mind, with its infinite afflictions, passions, and evils, is rooted in the three poisons. Greed, anger, and delusion.
Without the mind there is no Buddha. Without the Buddha there's no mind.
