Binaural beats are quite goo. I personally use Holosync–have been for almost 10 years now–and it’s been helpful. However, it must be supplemented by being present and unaided meditation.
Brainsync is also goo.
You can have all kinds of experiences when you meditate. Not fixed–varies by person.
But also, these beats, mostly only the aspect of bpm and hertz, require the user to focus still, once focused properly it will activate your brain to go into dream state, but if you cant sit still and meditate for 20 minutes then don’t expect much… there are tons of videos like “open your third eye meditation” but honestly by clicking on stuff like that and asking “is my third eye open now?” You’re basically putting absolutely no work into your craft and expecting something or someone to do all your work for you… so these are good tools, but only if you can meditate. Or else youre not really doing much except waiting around impatiently expecting it to “work”
