Devanagari from Sanskrit Wikisource; identical word-for-word with the GRETIL IAST e-text (prasasādodayād ambhaḥ kumbhayoner mahaujasaḥ / raghor abhibhavāśaṅki cukṣubhe dviṣatāṃ manaḥ).
'Jar-born' - a synonym of Agastya, distinct in form from the Amarakosa's Kumbhasambhava already in the database. The star-sense here is decisive and this is the single best kavya witness to Agastya as the autumn marker and clearer of waters: the verse turns on udayāt, 'from the RISING' (i.e. the heliacal rising of Canopus), the effect is that the water grew clear (prasasāda ambhaḥ), and the surrounding stanzas 4.17-4.24 are a set-piece description of śarad (autumn), closing with 'śarat urged him to the march'. A sage does not rise; a star does. Kalidasa elsewhere uses kumbhayoni / kumbhajanman purely of the SAGE Agastya in the Rama cantos (13.36, 15.55, 16.72), so the same word carries both senses within this one poem - the discriminator is 'udayāt' plus the water-clearing.
