(1) The more we awaken the different levels of our soul to Godliness, the more effect our prayers and Torah have on all the levels of our soul.
(2) In order to overcome obstacles in arousing oneself to prayer or Torah, one needs to draw the flames of Torah down into the deepest recesses of oneself.
These aren't exactly the things Rav Ades said, but this is the best understanding of it I could grasp. I've been trying to implement these teachings in my daily Tanya study. (I normally learn the daily Tanya lesson twice each morning) The first time through the daily lesson, I intend to awaken my soul as much as possible until even my toes want to be involved in the learning. The second time through, I learn with a fierce fire and passion to burn the words deep into my heart.
Rav Ades explained also the idea that the splitting of the sea was only in the merit of Yosef HaTzaddik. He said something to this effect, "Imagine, as the result of one man's holiness, the whole Jewish people survived and escaped."
