Rabeinu speaks about the importance of Viduy Devarim/verbal confession and why a person needs to express/describe his sins using his speech. Rabeinu connects this to the performance of mitzvot with joy and explains that in order to break all the obstacles in verbal confession (whether it might be forgetting the sin, or that it’s heavy on you to speak about it, etc…) one needs to arouse within oneself the joy of the mitzvah!
