If an associate gave you a gift of $100,000, would you be bitter? Of course not. You’d be very grateful. If that associate then gave $250,000 to a mutual friend of yours, you shouldn’t be resentful because they got more than you. You got $100,000! You will make the most of it.
Now, if someone you deeply care for appears to give more affection to a mutual friend, you shouldn’t feel bitter about that. That friend may be more needier than you, as you are much closer to more people than your friend is. Enjoy to the fullest the love you share with the one you care for. It’s special. Be grateful you have that. And your soul will make the most of it.
