For the Ascension of the soul of Maran Ha-Rav Kook

Q: I was at a class on the yahrzeit of Maran Ha-Rav Kook – 3rd Elul – and the Rabbi said that we are learning for the ascension of the soul of Maran Ha-Rav Avraham Yitzchak Ha-Cohain Kook. Can Maran Ha-Rav Kook's soul still ascend? Isn't he dwelling at the highest possible place a person can be?
A: This is true, but when Maran Ha-Rav Kook's students learn his Torah in his merit, this certainly causes his soul to ascend, whether you say: "For the ascension of his soul" or you do not say it. The greatness of Maran Ha-Rav Kook is not only what he did in his life but all of his students and his students' students which are in his merit.
