They seem to overlap.
In my experience, playing Hakuin’s Healing Egg Enhanced more often than once per hour may cause discomfort.
This may be related to the higher vibrational state of chi and flow of energy in excess or clashing, amongst other things.
From the description:
The inside of the ‘egg’ has higher vibrational state of chi, that also travels down from your crown from the inside, recharging your organs while removing energetic debris.
I’ve been enjoying experimental modified versions of daily playlists and @_OM and @Maoshan_Wanderer’s nightly stacks with Hakuin’s Healing Egg Enhanced added.
Every 70 to 80 minutes (or even less often) seems to be enough.
