“When the mind reaches that level of stillness, it’s not enough—the stillness of tranquility. You have to make it still through insight. You have to give rise to discernment. With the stillness of tranquility, it’s like not being able to be still in a hot place. You have to go to the seaside to be still. When you go back to where it’s hot, you’re not still anymore. The preoccupations of tranquility are only on this level of stillness. But with the preoccupations of insight, then when it’s hot in the mountains, you can stay there comfortably. When you go down to the seaside, you can stay there comfortably. You can focus on knowing these things, and the mind doesn’t run. It knows pleasure; it knows pain. That’s how we know when we practice.”
