A devoted man invited the Buddha to his house for a meal. After the meal, the Buddha delivered a sermon describing five immediacy-deeds which include matricide, patricide, killing an Arahant, causing a Buddha to suffer a contusion, and causing a schism in the Order. The five immediacy-deeds are called Anantariya-kamma and are heinous crimes that will have immediate, uninterrupted and uninterruptible effects.
