The Lotus Sutra is one of the oldest and most central sutras in Mahayana Buddhism. The sutra states repeatedly that people who perform small acts of devotion, such as making an offering at memorial to the Buddha, "have fulfilled the Buddha Way." What does this mean? I think the Lotus Sutra, and Mahayana Buddhism more generally, is saying that we can transform the universe in an instant, that the smallest of our actions matters, and that the key to all of it is the state of our own mind and heart.
