Slightly off-topic, but manifestation is the biggest bullshit out there. I agree that having a positive mindset can significantly influence how you experience life. But what the Law of Attraction and manifestation suggests is basically that whatever you think, you will bring into your life, which is why you must be in control of your thoughts at all times. Like attracts like, your thoughts become your reality. This also means that those living in poverty, those who go through traumatic experiences, are terminally ill, etc. somehow attracted these things into their lives, they “asked the universe” for these terrible situations.
As someone who suffered from intrusive thoughts for years, I can confidently tell you that no, your thoughts do not become your reality, and it’s a myth that we can or even should be in control of them for every second of our existence. My OCD made me think the worst thoughts, and back then, I thought I would end up somehow manifesting or attracting these horrific scenarios into my life because I couldn’t stop obsessing over them. This only made things worse.
That’s why the whole concept of manifesting/law of attraction is so toxic to me - it simplifies everything down to your own self, completely disregarding any other external factors.
