A short [syllable, i.e. a syllable with a short vowel], when not followed by a consonant cluster, is [metrically called] light. [Any] other syllable [is called] heavy. [A syllable with] a nasalized [vowel is] also [heavy]. Also at the end of a word [before pause, as in the Padapāṭha, a syllable is considered to be heavy]. (pp. 185-190) - Deshpande (1997)
