Religion is the opium of the masses.

You don't look out there for God, something in the sky, you look in you.

All of us have a God in us, and that God is the spirit that unites all life, everything that is on this planet.

Doubt is a pain too lonely to know that faith is his twin brother.

There are two kinds of people: those who say to God, 'Thy will be done,' and those to whom God says, 'All right, then, have it your way.'

Let him who is without sin cast the first stone.

It doesn’t matter what you say you believe - it only matters what you do.

Remember that when you leave this earth, you can take with you nothing that have received-only what you have given.

God is not a diversion.

The world is my country,all mankind are my brethren,and to do good is my religion.

We tend to think of prayer, in spite of ourselves, in terms of profit and loss.

If you're really spiritual, then you should be totally independent of the good and the bad opinions of the world... you should have faith in yourself.

I believe in God, only I spell it Nature.

This is my simple religion. There is no need for temples; no need for complicated philosophy. Our own brain, our own heart is our temple; the philosophy is kindness.

The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks.

God's house must be clean, otherwise, God will just run away.

You cannot believe in God until you believe in yourself.

God is a concept by which we measure our pain.

Spiritual progress is like a detoxification

It is always more difficult to fight against faith than against knowledge.

Everyone who has ever built anywhere a 'new heaven' first found the power thereto in his own hell.
