Has anyone gotten past the point of going to the bathroom and meditating in the hot springs? Every time I talk to the receptionist, she says I need to shower, but it's just a quick shower and nothing 
I recently replayed version 0.74.008, available here, because someone there couldn't complete this stage of the game in 100 in-game days. The stage involving awakening Celestian abilities took me four (4) in-game days.
I did what Kimiko says: shower, bathe, and meditate a lot every day. And Nel's help is a must.
So, be a little more attentive to what other characters in this game say. :-)
