Flit’st thou thus midway passion’s slave and jest, 
When all so near, above, below, unchanging
Are Heaven and rest?

And all human peace is in some sort won by conflict and maintained by energy:  it is never the triumph of inertia:  it represents the victory of purpose over circumstance. 

The whole universe in which we live is arranged in such a fashion that, if we would be at all in harmony with it, we must have patience.

The true felicity of life is to be free from perturbations;  to understand our duties towards God and man;  to enjoy the present without any serious dependence upon the future.

Noisy go the small waters, silent goes the vast ocean.

You will succeed best when you put the restless, anxious side of affairs out of mind, and allow the restful side to live in your thoughts.

If you are going to make your present happiness depend on incalculable elements, you might as well be happy as miserable.

Look straight into the Light, and you will always have the shadows behind.

Some of your griefs you have cured,
And the sharpest you still have survived,
But what torments of pain you endured,
From evils that never arrived.
