Pādukāvagga

Vinayapiṭaka · Parivāra · Vol. 8 · Section 231

[231] For one who, out of disrespect, teaches the Dhamma to a person seated clasping the knees (pallatthikā), there is an offense of wrong conduct (dukkaṭa) … There is one rule (paññatti) and one supplementary rule (anupaññatti). Of the six origins of offenses (āpattisamuṭṭhāna), it originates by one origin: it originates from speech and from mind (citta), not from body.
