[A]s humans, death remains unavoidable. The pain and sadness experienced by a natural death is no different from that brought on by sickness or war. Hence, since the outcome is unchangeable, it is imperative that we entrust our lives to the Lotus Sūtra.

Think of it as returning a drop of dew to the ocean or burying a speck of dust in the earth. The third fascicle of the Lotus Sūtra (chapter 7, “The Parable of a Magic City”) claims:

“May the merits we have accumulated by this offering
Be distributed among all living beings,
And may we and all other living beings
Attain the enlightenment of the Buddha together.”

With my deepest regards,
