Sacca-kiriya

thumb|The motif of the sacca-kiriyā presumes a natural moral force operating in the world. Sacca-kiriyā (Pāli; , but more often: satyādhiṣṭhāna) is a solemn declaration of truth, expressed in ritual speech. Most often found in Buddhism, it can be an utterance with regard to one's own virtue, or with regard to a certain fact, followed by a command or resolution. Such a statement is believed to effect a wonder-working power that can benefit oneself and others, depending on the truthfulness of the person making the statement. The sacca-kiriyā is a motif found in the scriptural stories from the Pāli Canon and its commentaries, as well as in post-canonical works such as the Milindapañhā and the Avadānas. In these stories it is found usually as a blessing, but sometimes as a curse. The motif can also be found in Hindu and Jain texts.

The sacca-kiriyā presumes a moral force of truth that is operating in the world, and is stronger than gods or humans. Although sacca-kiriyā often refer to characteristics of the Buddha, the Buddhist teaching, and the monastic community, it can also refer to facts with regard to natural phenomena, such as the sun or the moon. Some scholars believe that the effectiveness of a sacca-kiriyā as portrayed in stories depends on virtue and good character, whereas other scholars understand the sacca-kiriyā to be merely about speaking according to facts. Scholars theorize that the sacca-kiriyā is an ancient belief that precedes Buddhism, but was used in Buddhism as a teaching device to explain Buddhist ethics and other teachings. The principles underlying the sacca-kiriyā have also been connected with Mahatma Gandhi's ideal of non-violent resistance, and many other aspects of Asian culture and religious life.
