In corporeality, we see that raising the feet off the ground implies vitality, for Raglayim [legs] imply Meraglim [spies], who went to tour the land. They went to see if it was worthwhile to make an effort to be rewarded with the land of Kedusha [holiness]. Within reason, there are always views that are opposite from Kedusha, but we need to believe above reason that it is a land flowing with milk and honey.
Therefore, when lifting the feet off the ground and going above reason, there can be joy, even though there are ups and downs.
However, the broken is not more than the standing; rather, the ascents and descents change rapidly, so the periods of joy never go away.
