Knowledge
Now that I know
How passion warms little
Of flesh in the mould,
And treasure is brittle,--
I'll lie here and learn
How,over their ground
Trees make a long shadow
And a light sound.
Knowledge
This thing is used by everything
Throughout the world and throughout life
It is passed on from generation to generation
It is what keeps alive all who live
The key to life and survival
The key that opens the door to opportunity and
technology
