I have seen this on PI I think Giovani and some other members discuss it but I've forgotten where & also Jo was talking with me about this so thank you!
Using Theta waves with affirmations.
Maybe it will not be everyone's bag but basically the theory is that when we are in an Alpha state (this is normal, it's like when we are closer to sleep, when we zone out a bit) or Theta (even deeper) we can be more receptive to affirmations.
So I've been listening to some Theta vids on youtube & also very recently I've been exploring playing some Theta waves on youtube while also listening to affirmations. I feel like I AM more receptive & DO get a bit of a boost, like I feel it more but your mileage may vary, just something to explore if you are interested.
They don't SOUND like anything much heck some Theta sounds like a very quiet helicopter! but some people say it can give affirmations a manifesting boost! I will share some Theta vid links if anyone wants.
