What does Tupac's The Power of a Smile really mean?

Hello,
I was trying to analyse this poem:
The power of a gun can kill
and the power of Fire can Burn
The power of wind can chill
and the power of the mind can learn
The power of anger can rage
inside until it tears u apart
But the Power of a Smile
especially yours can heal a frozen Heart

I know it is ABAB format, however, I'm confused a little bit on what it truly means, and what heightened use of imagery, and sound linkages there are here.
