तस्यार्धमायुषो रात्रिर्हरते मृत्युरूपिणी । बालभावेन मोहेन वार्धके जरया तथा
tasyārdhamāyuṣo rātrirharate mṛtyurūpiṇī | bālabhāvena mohena vārdhake jarayā tathā
Half of that lifespan is taken away by night itself—death in that form. And what remains is lost in childhood through immaturity and delusion, and in old age through decay as well.
Lomaharṣaṇa (Sūta) to the sages
Scene: An allegorical scene: Night as a dark, veiled figure silently taking away half of a man’s lifespan; beside him a child lost in play (moha) and an aged figure bent with jarā, showing the remaining life slipping away like sand.
Life is effectively shortened by sleep, delusion, and aging; therefore one should use the waking, capable years for Dharma and spiritual striving.
No Tīrtha is mentioned in this verse.
None; it is a reflective teaching meant to inspire urgency and discipline.
