The penultimate of the Causative of hlad (hlādi) is shortened before the Participle affixes kta and ktavatu,
Thus प्रह्लन्नः, प्रह्लन्नवान्, but प्रह्लादयति before non-nishtha. The rule applies also when क्तिन् follows as प्रह्लत्तिः ॥ This is done by splitting up the aphorism into two (1) ह्लादः (2) निष्ठायाम् ॥,
