Indestructible..

A man of great wealth
A man of great stature 
A man of ripe age
told me once in a moment of earnest affection

Gather wealth
It may be dwindled by expense
it may wither in a season of misfortune
it may fall prey to cunning and thievery

Instead he said, Gather Knowledge
for unlike wealth it can never be stolen
Indestructible is Knowledge
In dispense it shall multiply
In seasons difficult it should be your friend

Indeed Learned ones profess,
In Scholarship and humility 
Lies true Wealth
