A person devoted to their own natural duty attains perfection. This verse establishes svadharma — following one's own nature — as the direct path to fulfillment. Shankara teaches that perfection through one's own duty means the purification that leads to knowledge. Ramanuja sees it as the Lord's personal assurance that every soul's path, faithfully followed, leads to Him. Madhva teaches that the Lord has designed each path, and following it with devotion ensures both welfare and progress. Abhinavagupta reads it as meaning each person's unique consciousness-configuration is itself the path — there is no generic route to recognition. Vallabha teaches that one's natural duty is God's customized path of return for each soul. The bhakti tradition celebrates that any devotee, in any walk of life, can attain perfection through devoted engagement. Tilak considers this foundational: perfection comes from quality of engagement, not type of work. Vivekananda teaches that following natural aptitude leads more surely to fulfillment than imitating another's path. The verse is both liberating and demanding: you need not be anyone else, but you must be fully yourself.
