Sanatkumāra said - ‘When a person keeps doing his duty, he becomes steady. If one does not do one’s duty, one cannot have steadiness. One attains steadiness by doing one’s duty. But one should try to know what duty means.’ Nārada replied - ‘Sir, I want to know about duty’.
Chandogya
The Chandogya Upanishad is notable for its lilting metric structure, its mention of ancient cultural elements such as musical instruments, and embedded philosophical premises that later served as foundation for Vedanta schools.
