accusative singular neuter of pariyosānakalyāṇa (adjective/noun)
Analysis. pari- (around, all the way round) + yosāna (ending, conclusion) + kalyāṇa (beauty, goodness); the compound expresses completeness and excellence brought to full conclusion.
Etymology. pari- prefix expressing totality; yosāna from √yas (to become exhausted, end); kalyāṇa from PIE *kel- (to excel, be beautiful), cognate with Greek kallos (beauty). The prefix pari- preserves its spatial sense of 'all the way round' as it becomes the abstract notion of completeness.
