Am writing to ask in the retrospection meditation about the mantra WU should it be practiced during meditation or after meditation I don't seem to understand and the instructor said everyday.
(1)should be said at the same time am remembering the events seems to be calming but not really sure it's purpose

(2)won't saying the mantra WU kinda affect what I will be remembering like what I said ?

(3)what really is the purpose of the mantra WU said its to probe the subconscious?is it like to remember events like mantra RAOM GAOM or to easily bring out how the ego where acting at that moment
