“The key is to let go of two things: grasping and aversion. Grasping is when the mind desperately holds on to something and refuses to let it go. Aversion is when the mind desperately keeps something away and refuses to let it come. These two qualities are flip sides of each other. Grasping and aversion together account for a huge percentage of the suffering we experience, perhaps 90 percent, maybe even 100 percent.”
