D'var Torah: The Zohar reveals, "Attaining clarity that HaShem is the Source of all Goodness is a great virtue. What's more, when a person recognizes that HaShem bestows unbounded goodness upon him, he will acquire a 'good eye" (Zohar Bereisheis 197). What is the relationship between realizing the Goodness of HaShem and developing a "good eye"? A cursory understanding of HaShem's goodness does not suffice to open our hearts with pure joy. The Zohar reveals a definitive test to clarify if we genuinely recognize the goodness of HaShem. If the unbounded goodness of HaShem fills our hearts with great happiness, then we will be happy for the success of our friends.
Moral: When we make a consistent and concentrated effort to rejoice in the goodness that HaShem always showers upon us, then we will be delighted with all the good that comes to our friend.
Application: Before you eat your meal, take a few moments to appreciate the kindness of HaShem. Say your blessing with heartfelt joy. Enjoy the life-giving sustenance of HaShem's food. Make your after blessings with thanks and praise to HaShem -- the Source of Good. Rejoice in the good that comes to your friend.
