We might think that the answer is simply to stop davening and contemplating so much and just focus on doing what Hashem wants. However, the Maamar teaches us otherwise. It is not enough to change focus from davening and spirituality to practical performance. There needs to be a point of reconnection, where he reawakens his passionate desire to transcend the limitations of physicality and directs it towards fueling a new commitment to action. This is the only way to draw his spiritual accomplishments into something that is helpful in the practical sense. Otherwise, he will be unable to fully devote himself to fulfilling the Torah and mitzvos in this world. Instead, his previous mindset and feelings will constantly draw him back into his old approach to serving Hashem, the incorrect approach that resulted in his Tzaraas in the first place. In order to be healed of the external expression (the Tzaraas), he must be rid of the internal attitude and perspective that caused it.
