When you have learned,
You cast your own shadow.
And you then lift your head towards the Sun,
To notice none.
That is where your strength comes from.
Keep it energized.
Unrestricted with ambitions you wish,
To fulfill a cloudless happiness...
Inside your mind where that is carried.
Lawrence S. Pertillar
