Chessed L'Avraham Arizal Shabbos from rimon 26 part 2 rimon 27 mikveh part I

Taking Shabbos into the days of the week; Shnayim mikra; Chayay Adam that you will feel the light of Shabbos after the mikveh; that the Ramchal did not go to the mikveh erev Shabbos and what he writes about this; Today you cannot have kavanos in the Mikveh room but you can under the water (didn't go into Rav Shlomo Kluger about this, maybe next time)
