It really is all subjective. Some things work better than others or just don’t work at all. But then, a certain variation can end up working. This is even the same with over the counter or prescription drugs as everyone tends to have varying experiences with them. But with subtle energies, the subjectivity is even more so because subtle energies are affecting you through the thinner layer of reality where thoughts are a lot more concrete. Our thought patterns, limiting beliefs, ext… all tend to have an effect on the way morphic fields affect us. This is why quite often, there is subconscious resistance.
So if the day you decide to begin to listen to an audio, you go in with conflicting thoughts or a certain mood, those thoughts may influence the audio to not produce noticeable results… which might snowball into it not working at all. That being said, the opposite is very true as well. It could still work despite such thoughts which it has for most listeners. So don’t begin to worry about your thoughts while listening.
We have recently been working on finding ways to circumvent subconscious resistance. If you have trouble with an audio, try this. While listening, say ‘I ask my subconscious to engage and accept this energy at this moment I am listening to this.’ It’s small enough of a window that it will pay attention and let it happen, then revert back after. Try this out if you begin to have subconscious resistance.
