Sanatkumāra said - ‘When a person knows for certain, then he can truly speak of the Truth. But without knowing well, he cannot speak of the Truth. One who knows for certain speaks of Truth. But one must seek knowledge in depth.’ Nārada said - ‘Sir, I seek knowledge in depth’.
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.
