“What we normally call the mind is the deluded mind, a turbulent vortex of thoughts whipped up by attachment, anger, and ignorance. This mind, unlike enlightened awareness, is always being carried away by one delusion after another. Thoughts of hatred or attachment suddenly arise without warning, triggered by such circumstances as an unexpected meeting with an enemy or a friend, and unless they are immediately overpowered with the proper antidote, they quickly take root and proliferate, reinforcing the habitual predominance of hatred or attachment in the mind and adding more and more karmic patterns.”
