Sutala. Located in the knees, it governs jealousy.

 

 

• Jealousy:
  Jealousy is directed at another person who has something you want.
  The negative aspects of the emotion are more complicated, but that
  is its two core components.

• Be Reactive:
  Choose how you react! First consider the inner element: what you
  want. What are you jealous of?
  This will identify your need. Then consider the target of your
  jealousy. Why are you jealous of that
  person when he or she is not the only one with that
  success/object/etc? Answering this question will probably reveal
  that this person has several attributes or possessions that you want
  – not just one.

• Be
  Proactive:
  Change how you act! Feeling jealous and acting jealous are two
  different things, but why do either if you don’t have to? You know
  it isn’t the other person’s fault and you know not to take it out on
  him/her. Look at this as a challenge to you to be the next (or
  tenth) person to earn that achievement. If you want it enough to be
  jealous, then it surely is worth working hard for. Then people can
  be jealous of you! (Just joking, really!)
