"A SECRET"
O boy! A secret necessary to be concealed from a foe
Thou wilt do well not to reveal it even to a friend.
I have seen many who in course of capricious time
Became foes from friends, and amity to enmity turned.
"THE INDISPENSABLE KNOWLEDGE"
Cultivate the knowledge which is indispensable to you,
And seek not that which you can dispense with.
From the moment you acquire the indispensable knowledge,
You must not desire to act except in accordance therewith.
