Happiness is self-generated. It depends on one's attitude of mind. The basis of happiness, is the simple fact that the deepest reality of our own nature is ever-existing, ever-conscious, ever-new joy.
Happiness is a smile of comfort to the sorrowful.
Laughter is a medicine you've got to use to drive away blues.
Happiness is understanding that friendship is more precious than mere things, more precious than getting your own way, more precious than being in situations where true principles are not at stake.
Learn to live more in the Self. Come down a little bit to eat and talk as necessary.
We've got to be long distance runners on the spiritual path. We want to run as fast as we can, but at the same time realize that if God isn't at the end of that 100 yards, we don't fall flat of exhaustion. We've got to have whatever rhythm it takes to be able to go on for incarnations until we find that state of perfection we've been seeking.
Take whatever cause for outward happiness you might have and take it within yourself, so that, if the sun should go out, you will not be any less happy; if the birds stop singing you will not be any less happy.
Feel that you are happy without any cause for happiness.
To be happy, you must live in, but not for, the present moment.
