הרצון (will) comes with two meanings: a) from the theme of appeasement like כי נרצה עונה (that her guilt is paid off)⁶⁴² b) from the theme of desire.

footnotes: ⁶⁴² Isaiah 40:2.

And there is a difference between חפץ (desire) and רצון (will): חפץ is through the tendency of the soul. On the contrary, רצון is from the free will of the mind and is clean from all tendencies of the soul. And one can conceive of a man who רצה a certain object but does not חפץ it, and vice versa.

רצון is an intellectual desire, while חפץ is an emotional or physical desire. For example, one canרצהto eat only kosher food for the reason that the Torah says to only eat kosher food, but one may still חפץ non-kosher food because he desires the taste.
