Lomashishiksha 8

When ya and va are joined with r, if the r is first, / one should understand it as belonging to the preceding limb; 'sūrya' is an example of the preceding.

When ya and va are joined with r, and if it occurs at a pause, / one should understand it as belonging to the following limb; 'aro harya' is the defining instance.

From āsannāt, mahānāt, and yātudhānāt, as they occur, / the wise teach that these do not take a preceding n-sound.

Wherever the letter h is seen joined with the class-nasals, / they are understood as beginning with ut, and one should realise them joined separately.

A letter h preceded by r, or even following after r, / [or] where h follows an anusvāra—it duplicates (kramati) in these three [positions].

The sounds śa, ṣa, and sa following an anusvāra never duplicate; / śa, ṣa, and sa duplicate there if followed by semivowels.

Where a speck resembling a ray of the sun is seen, / that is the measure of an atom (aṇu); but a mora (mātrā) consists of four atoms.

One should know [the sound] residing in the heart as an atom; in the throat, one should know it as two atoms; / as three atoms at the tip of the tongue; released [forth], it becomes one mora.

The blue jay utters one mora; the crow has declared two morae; / the peacock is to be known as having three morae: this is the comprehension of morae.

A short [vowel] has one mora; a long [vowel] is said to have two morae; / a prolated [vowel] is understood as having three morae; and a consonant has half a mora.

Everything here is a fourth; they do not increase; these increase: / as in daścarati, rāndrasvindrasacchū, atapasātvāsūgolārātpatantī, and in the secret text / of varhirṣya etc., there is non-circumflexion, elision of the consonant, elision of the consonant.
