"A true war story is never moral. It does not instruct, nor encourage virtue, nor suggest models of proper human behavior, nor restrain men from doing the things men have always done. If a story seems moral, do not believe it. If at the end of a war story you feel uplifted, or if you feel that some small bit of rectitude has been salvaged from the larger waste, then you have been made the victim of a very old and terrible lie. There is no rectitude whatsoever. There is no virtue. As a first rule of thumb, therefore, you can tell a true war story by its absolute and uncompromising allegiance to obscenity and evil."

I took the path more traveled by

"Everyone wants to be happy. But we may suffer a lot trying to be happy. We need the insight that position, revenge, wealth, fame or possessions are, more often than not, obstacles to happiness.

-- Thich Nhat Hanh

This is the work of meditation."

The world is horrible and I am lonely
Let me rest here where yellow roses bloom
And find forgetfulness, remembering only
Your face beside me in the scented gloom
Give me, o you whose arms are soft and slender
Whose eyes are nothing but one long caress
Against your heart, so innocent and tender
A little love, and some forgetfulness

If you have food in your fridge, clothes on your back, a roof over your head and a place to sleep, you are richer than 75% of the world.

If you have money in the bank and some spare change in your wallet you are among the top 8% of the world's wealthy.

If you woke up this morning with more health than illness, you are more blessed than the million people who will not survive this week.

If you have never experienced the danger of battle, the agony of imprisonment or torture, or the horrible pangs of starvation, you are luckier than 500 million people who are alive and suffering.

If you can read this message, you are more fortunate than 3 billion people in the world who cannot read at all.

"The whole pace of our lives is hectic. The last thing we have time to think of is death.

I am subject to aging. Aging is unavoidable.
I am subject to illness. Illness is unavoidable.
I am subject to death. Death is unavoidable.
I will grow different, separate from all that is dear and appealing to me.
I am the owner of my actions, heir to my actions, born of my actions, related through my actions, and live dependent on my actions. Whatever I do, for good or evil, to that will I fall heir.
We should reflect on this often."

2012, hiking outside of Big Sur, California

"Our true home is in the present moment. To live in the present moment is a miracle. The miracle is not to walk on water. The miracle is to walk on the green Earth in the present moment and appreciate the grace and beauty that are available now. Peace is all around us, in the world and in nature, and within us, in our bodies and spirits. Once we learn to touch this peace we will be healed and transformed. It is not a matter of faith, it is a matter of practice."
-- Thich Nhat Hanh
