naratvaṁ durlabhaṁ loke vidyā tatra sudurlabhā |
kavitvaṁ durlabhaṁ tatra śaktis tatra sudurlabhā||
(Agni Purāṇa; cited in Sāhitya-darpaṇa: 1.2)
“In this world, human life is rare, and therein [i.e., among human beings] education is very rare. Therein [i.e., among the educated], being poetic is rare, and therein [i.e., among the poetic], prowess [in poetics] is very rare.”
