When it is a person's first Akashic Records session with me, I always start by advising them to take notes. Everything is so easy and breezy when we are in the Records, it is hard to imagine that you would ever forget anything the Guides say; however, the details slip away, time passes, and you just kinda forget.
Here are three reasons that notes are an essential part of an Akashic Session:
Memory Booster
Writing is shown to cement information in the mind. If you are taking notes in a session, you are more likely to remember it!
Rereading Brings Understanding
When was the last time you reread your Akashic Records notes? Reading through all of your notes every few months is incredibly helpful. There are some things that you simply forget that then have the opportunity to become re-established in your mind.
Also, there are some things that pop up during a session that simply do not resonate at the time. I have definitely been in a session with my beloved teacher when she shared something that felt totally off. I've smiled warmly, jotted it down politely, and simultaneously thought, "Nope - that is not right at all." Wouldn't you know, 6 months down the road, I reread my notes and everything suddenly made sense. (A complete I-told-you-so moment for my Guides.)
Evidence of Progress
If you make a habit of taking notes during sessions, you will end up with a journal that shows your progress through the months/years. Aside from simply being a really cool thing, it also works to boost your confidence. Transformation is (usually) a slow process. We can't tell it's happening in the moment. Having these journals will provide you with evidence of how you have changed. You'll have moments of thinking, "Wow - I forgot that I used to have that pattern!" It provides the needed inspiration to continue on our paths.
In summary, to echo your high school history teacher, just take the notes! You'll be happy you did.
