Cherokee elder tells story to grandson:

"There is a battle between two wolves inside us all."
"One of the wolves is full of of anger, envy, jealousy, regret, greed, arrogance, self-pity, resentment, lies, false pride.
The other wolf is full of joy, peace, gratitude, love, serenity, kindness, generosity, compassion, humility, benevolence."

The grandson is in deep thought for a moment and then asks his grandfather:
"Which wolf wins?"

The Cherokee elder replies: "The one you feed."

Happiness

Happiness needs no reasons. Unhappiness needs reasons; happiness is simply natural. It is one's very nature that one should be joyous. To be unhappy, reasons are needed, but just to be happy, no reasons are needed. Happiness is enough unto itself. It is such a beautiful experience, what more do you need? Why should you need any cause for it? It itself is enough:it is a cause unto itself.

"The only thing which we all have in common is that we play tricks on ourselves which force us to abandon our quest. The counter measure is to persist in spite of all barriers and disappointments. If one is to succeed in anything, the success must come gently, with a great deal of effort, but with no stress or obsession." - Carlos Casteneda

"With courage you will dare to take risks, have the strength to be compassionate and the wisdom to be humble. Courage is the foundation of integrity." - Keshavan Nair
