A Simple Jew commenting on Akiva Answers :
To answer my own question simply, the lesson my strongest taiva teaches me is single-mindedness.
At the times when my strongest taiva is successful in luring me to indulge, it short-circuits the communications to my brain, takes command of my thoughts, and directs them solely to fulfilling its aim. Just as my Divine soul desires that all my physical organ's become a merkava (chariot) for it to perform its will, so too does my strongest taiva desire that my all my organs become merkava for its decadence.
So, what can I learn from this and apply it to my avodas Hashem?
I learn that my yetzer tov must use exactly the same tactics as the tactics of my yetzer hara. In Pirkei Avos 4:1, Ben Zoma taught that the wise man learns something from every person. However, the Degel Machaneh Ephraim taught that the wise man must learn even from his yetzer hara.
If my yetzer hara is repeatedly successful by taking control of my thoughts, shutting out conflicting stimuli, and propelling me to fulfill its aims, then I know that my yetzer tov has to do precisely the same thing. If I trust 100% that Hashem runs the world and that He gave us the Torah, I should be single-minded in fulfilling what He wants me to do. If a contradicting thought pops into my mind in the guise of being a "rational" thought, I should laugh and push it aside, since its aim is not my aim.
My aim is to fulfill the unique mission that my neshoma was sent down in this world to fulfill. My strongest taiva's tactics remind me that I can only hope to accomplish this mission if I remain single-minded and passionate to fulfill it.
