In the Buddha’s time, a devoted man invited the Buddha to his house for a meal. After 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 schism in the Order. The five immediacy-deeds called Anantariya-kamma which are heinous crimes and bring immediate, uninterrupted and uninterruptible results.
