Longing or yearning is a strong desire for something. It can be something physical/tangible or intangible. Kabbalist Baruch Ashlag (Rabash), in Letter 21, writes the following: “Baal HaSulam said that everything is insipid unless there is a desire and an appetite for it, called ‘yearning.’” In this episode of The World, hosted by Norma Livne, Kabbalist Dr. Michael Laitman will discuss what is a yearning for spirituality according to the wisdom of Kabbalah.
