Guru Nanak

If the people use the wealth bestowed on them by God for themselves alone or for treasuring it, it is like a corpse. But if they decide to share it with others, it becomes sacred food.

If there is one God, then there is only His way to attain Him, not another. One must follow that way and reject the other. Worship not him who is born only to die, but Him who is eternal and is contained in the whole universe.

Asceticism doesn't lie in ascetic robes or in walking staff nor in the ashes. Asceticism doesn't lie in the earring nor in the shaven head nor blowing a conch. Asceticism lies in remaining pure amidst impurities.

By singing the Guru's hymns, I, the minstrel spread the Lord's glory. Nanak, by praising the True Name, I have obtained the perfect Lord.

Riches cannot be gathered without sin and evil means.

One cannot comprehend Him through reason, even if one reasoned for ages.
