Caitanya-caritāmṛta 18.14
koṭi-yuga paryanta yadi likhaye gaṇeśa eka-dinera līlāra tabu nāhi pāya śeṣa
[koti-yuga paryanta yadi likhaye ganesha eka-dinera leelaara tabu naahi paaya shesha]
Blended reading (Sanskrit + English inline)
koṭi-yuga paryanta yadi likhaye gaṇeśa eka-dinera līlāra tabu nāhi pāya śeṣa
If Gaṇeśa, Lord Śiva’s son and the expert scribe of the demigods, tried for millions of millenniums to fully describe one day of the Lord’s pastimes, he would be unable to find their limit.
