Funny thing about placebo. It basically means your belief in something is enough to cause the result you desire. At the end of the day what is placebo and what isnt placebo?
Lets say I make a pill that cures headaches (lets say aspirin). I could explain to you in scientific terms how it will help but if I give it to you and it doesnt help then why does the science matter at all? The pill will be of no use to you regardless of the “science” of the matter.
Likewise, if I was a priest and someone came to my church sick with leprosy and I splash holy water (blessed salt water) on them and the next day they are cured, would it matter if the result was solely placebo derived? Jesus healed people because they had faith that he was able to do so.
What I’m trying to get at is everything is belief. If you want to manifest the results you desire you need belief, you need faith. Aspirin wont work on someone (even if it should) if they firmly believe it wont work. Jesus could only heal those with faith, those without faith would receive no miracles.
This doesnt mean Aspirin doesnt work, it just means that belief is the primary driving force of manifestation and the Aspirin is just one means of producing the desired result of losing your headache.
Like aspirin, these audios are simply a means for your subconscious to manifest your desire. The power is in you, it always has and always will be. Our external environment is just a means to create that which we desire in this reality.
