Regarding "when ac follows": But when the rule "nājjhalau" (Pā. Sū. 1.1.10) is rejected by relying on the slight open-ness (īṣadvivṛtatva) of the sibilants and h (ūṣman), then aci is not to be continued here; it can simply be stated: ako'ki dīrghaḥ. Regarding "two sounds [each of] two morae": As for what was explained by the older grammarian, that when a long vowel is obtained, short ṛ and lṛ are prescribed—that is to be dismissed, because it contradicts the Mahābhāṣya, Kaiyaṭa, and others.
