Sir Edwin Arnold on Katha Upanishad

The subtle thought, the far-off faith,
The deathless spirit mocking Death,
The close-packed sense, hard to unlock
As diamonds from the mother-rock,
The solemn, brief simplicity,
The insight, fancy, mystery
Of Hindu scriptures all are had
In this divine Upanishad.
