सर्त्ति-शास्ति-अर्तिभ्यः च

Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.

Commentary

After the words सृ 'to go', शास् 'to order' and ऋ 'to go', अङ् is the substitute of च्लि in the परस्मैपद as well as the आत्मनेपद ।
Thus असरत् 'he went'; अशिषत् 'he ordered'; आरत् 'he went'. This sutra has been separately enunciated in order to make the rule applicable to Atmanepada; as समरन्त 1.3.29. The च in the text is for the sake of drawing the anuvritti of the phrase 'in the Parasmaipada' of the last sutra, into the present and its anuvriti will extend to future sutras also.
