I came across this interesting map of emotions via FlowingData.

Now see how Patanjali’s Chakras aligns with above heat maps.

 My favourites are how Depression completely “switches off” activity in all chakras! Or how Happiness literally lights up the whole being, in fact even better than being in a state of Love!

Also, the similarity between states of Anger and Pride are interesting. And check how Anger makes the arms glow. Fascinating!
