It is human nature to want the best for yourself. You want to be happy. You want peace of mind. You want to live a comfortable life.
How do we get these things by helping others? This is the paradox of The Rule of Divinity. The Rule of Divinity states that everything is one and one is the greatest power.
Since everything (and everyone) is one, what you do for others you do for yourself. By helping others become happy, loved, and at peace, you are contributing to the greater you, the one great power, God.
The paradox works both ways: By helping yourself, you help others; by helping others, you help yourself.
So continue to help others while helping yourself. Working on the two together will help yourself and the world around you to become better.
