You have said, “I am not fatigued from labor.” Although the soul is different from the body, there is fatigue because of bodily labor, and it appears to be the fatigue of the soul. When you are carrying the palanquin, there is certainly labor for the soul. This is my conjecture. You have also said that the external behavior exhibited between the master and the servant is not factual, but although in the phenomenal world it is not factual, the products of the phenomenal world can actually affect things. That is visible and experienced. As such, even though material activities are impermanent, they cannot be said to be untrue.
