The compendium describes itself within a lineage: teachings associated with Atreya passed through Agnivesha, were reworked by Charaka, and were later completed in missing sections by Dridhabala. Scholars disagree over exact dates, and the surviving text contains material from different periods.
That history matters. A medical classic could remain authoritative precisely because editors, teachers, commentators, and copyists continued to organise and interpret it. “Charaka” can therefore identify a historical redactor, an attributed physician, and a durable scholarly voice without supplying a conventional biography.
The work's survival also depended on manuscript cultures and later print editions. Its modern status as a national or civilisational classic emerged through newer institutions, translations, regulation, and debates about how Ayurveda should relate to laboratory science and clinical trials.
