Open your heart to give; in order to receive

I was watching 'Clean House' on Style Network quite some time ago when the host said the following in order to convince someone to donate their unsold yard sale items to charity. It left a very deep impression in my mind. It goes:

If you open your heart to give, you will open your heart to receive.

I was struck by the simplicity of that statement, yet the profoundess of it.

Today, I came across this article in my rss reader about how to create the abundance mindset. It explains why the act of giving allows you to receive in return. Fully recommended. :)
