Hey Kenny
Haven't seen you here in a while, how you doin?
Anyway, regarding your query... both ways you mentioned are perfectly fine. It's just a matter of preference. These little rituals like shuffling, cleansing, meditating etc. with the cards are only done in order to create a bond with the deck of cards. They aren't set in stone rules about such things... just as long as you don't tear the cards up in the process
The method that you mentioned about spreading out the cards and putting them back together is quite good if you're working with reversals. But remember, only do whatever you feel comfortable doing
I do both, depending on my mood.
Hope this helps
Love and blessings
