The Perfection of Generosity.

The Compendium of the Perfections says:

If you see the impermanence of resources

And naturally have great compassion

You will know with good reason that the gifts

You have kept in your houses belong to others.

There is never fear from what has been given away;

What is kept at home gives rise to fears

That it is insufficient, ordinary, or needing contant protection.

If you give it away, these faults never harm you.

By giving you achieve happiness in future lives;

Not giving brings suffering even in this life.
Human wealth is like a shooting star-

What is not given away will cease to exist.

Wealth not given is transitory and will be gone;

By giving it away it  remains a treasury.
Wealth of no value comes to have value

When you strive to help living beings.

The wise praise giving wealth away,

Childish persons like to hoard it;

No wealth is kept by holding on to it;

From giving it away excellence always arises.

By giving things away, you no longer grasp the afflictions;

Being miserly breeds afflictions on an ignoble path.
Noble beings say generosity is the best path,

While its opposite is a bad path.
