Circe

“A belligerent samurai, an old Japanese tale goes, once challenged a Zen master to explain the concept of heaven and hell. The monk replied with scorn, "You're nothing but a lout - I can't waste my time with the likes of you!"
His very honor attacked, the samurai flew into a rage and, pulling his sword from its scabbard, yelled "I could kill you for your impertinence."
"That," the monk calmly replied, "is hell."
Startled at seeing the truth in what the master pointed out about the fury that had him in its grip, the samurai calmed down, sheathed his sword, and bowed, thanking the monk for the insight.
"And that,"said the monk "is heaven."

The sudden awakening of the samurai to his own agitated state illustrates the crucial difference between being caught up in a feeling and becoming aware that you are being swept away by it. Socrates's injunction "Know thyself" speaks to the keystone of emotional intelligence: awareness of one's own feelings as they occur.”

“If you currently travel abroad or plan to in the future, make sure you understand the cultural convention of the country that you are visiting. Particularly with regard to greetings. If someone gives you a weak hand-shake, don't grimace. If anyone takes your arm, don't wince. If you are in the Middle East and a person wants to hold your hand, hold it. If you are a man visiting Russia, don't be surprised when your male host kisses your cheek, rather than hand. All of these greetings are as natural as way to express genuine sentiments as an American handshake. I am honored when an Arab or Asian man offers to take my hand because I know that it is a sign of high respect and trust. Accepting these cultural differences is the first step to better understanding and embracing diversity.”

“Thus, what enables the wise sovereign and the good general to strike and conquer, and achieve things beyond the reach of ordinary men, is foreknowledge.”
