Question: I am confused by all the different types of Kaddish said in our prayer services. There is the Mourner's Kaddish, Rabanan Kaddish (Learner's Kaddish), Half Kaddish and Complete Kaddish. What is going on here?! If Kaddish is supposed to be said in memory of someone, why do we say it so many times throughout the service and have so many variations for the same prayer?
Response: All the various versions of Kaddish achieve the same purpose. With its mystically powerful words, Kaddish transports a soul upwards, from one level to the next. What distinguishes between the different Kaddishes is exactly who is being elevated.
The Mourner's Kaddish is recited for the departed, to assist in their soul's journey upward. For eleven months after passing away, the soul ascends gradually to its place of rest. And then each year, on the anniversary of its passing, the soul graduates to an even higher place in Heaven. The Kaddish said down here by the living assists the journey of the soul up there.
For this same reason we say Kaddish at different junctures in the prayer service. Our prayers are a ladder up. We begin our prayers on earth, solidly stuck on the ground. As we progress through the prayers we gradually climb higher, each section of the service taking us a little closer to heaven. The Kaddish serves its purpose here too - moving things upward to a higher place.
The Half Kaddish is recited between sections of the service, when the souls of those praying are about to ascend another rung and go to the next level.
The Complete Kaddish is said at the conclusion of a service, to deliver the words of prayer to higher realms.
And the Rabanan (Learner's) Kaddish is recited after studying a passage from the Talmud. Just as the Complete Kaddish delivers our prayers on high, the Rabanan Kaddish delivers our Torah study heavenward.
So next time you hear Kaddish, envisage this: your soul, the souls of your loved ones, your prayers and your Torah study are all ascending into heaven and assisting the soul through the cleansing of wrongdoings it may have done while in the physical world, while also raising it to higher levels within the Garden of Eden, what is often referred to as “paradise. There is also tremendous merit granted to all those in Shul who respond with each and every Amen to the Kaddish being said and refrain from any conversation while this very holy prayer is being recited.
