Thích Nhất Hạnh here quotes and interprets the "Ten Penetrations" of the Avatamsaka Sutra
The Sun My Heart (1996)
Context: The tenth penetration is, "All times penetrate one time. One time penetrates all times — past, present, and future. In one second, you can find the past, present, and future." In the past, you can see the present and the future. In the present, you can find the past and future. In the future, you can find the past and present. They "inter-contain" each other. Space contains time, time contains space. In the teaching of interpenetration, one determines the other, the other determines this one. When we realize our nature of interbeing, we will stop blaming and killing, because we know that we inter-are.
