Rabbi Akiva, who was the teacher and mentor of 24,000 students taught:

“וְאָהַבְתָּ לְרֵעֲךָ כָּמוֹךָ”

“Love your comrade as you love yourself — this is the primary principle of the Torah”

Our hearts are filled with emotion. We need to use our emotions for good; to love our friends, to forgive, to be generous, not to get angry, to be in high spirits when our friends are happy and to feel their pain, to develop sensitivities for when our friends need our help and to do favors for them. It’s possible to understand what are friends are feeling and to understand their needs even without the telling us exactly how their feeling. Sometimes we can figure these things out by the look on their faces.

You’ve read all about facial expressions and how they express our emotions. When staging a play we choose actors who know how to make faces that will get the play’s emotional message across to the audience. Would you like to try and be an actor?
