"স্বরিতঞিতঃ কর্ত্রভিপ্রায়ে ক্রিয়াফলে ॥" ২৬ ॥
"svaritanitah kartrabhipraye kriya-phale"
svarita-nitah-of verbs having an indicatory n or a svarita accent; kartrabhipraye-is meant for the agent; kriya-phale-when the fruit of the action.
" 'The terminations of the atmanepada are employed when the fruit of the action accrues to the agent of verbs having an indicatory n or a svarita accent.'
This is a quotation from Panini's sutras (1.3.72).
