Do you do chakra balancing? How and where to start?

[PsiloPutty]

I did a guided YouTube meditation yesterday on balancing my solar plexus chakra, but that's all the experience I have with it. I just went with that chakra because I have some guilt and shame to work through, and someone said that is the chakra to work with for that issue. 

Aside from feelings, how do you know which chakra needs work?
