It doesn't matter just how jealous you may be feeling, there are always methods to soften our feelings and return to a compassionate state. Keep in mind that emotions travel through us, they are not us. You are not jealous, you feel jealous. Try feeling something else, like joy. Another thought to consider is why do you feel so jealous? You should separate yourself from this situation and meditate on your feelings. You are clearly missing something important in your life that you feel would benefit you. Think about any changes you should make, but be careful, the grass isn’t always greener on the other side.
