The act of planting a 'mental anchor' is actually about accumulating good karma and karma.

For example, if someone is having a bad year, you can plant a 'fear anchor' in them, making them afraid and timid. As long as they avoid a big pit out of fear, that's virtue and good karma. The worst are those who can't get the anchor to take hold, half-believing and half-doubting, ultimately jumping into the pit themselves.
Honestly, making someone nervous all year is probably better than actually breaking their arms or legs, or ruining their family. Even if it’s a bit stressful mentally, at least they’re safe and their money is still there.
Just like some older brothers who consult me on Telegram, I also find it quite complicated. If I go too heavy, I worry it might affect their heart; if I go too light, they think ‘it’s nothing,’ but when their luck turns, they lose money or get scammed.
So I’ve come to understand that for personal accidents or scams like pig-butchering schemes, I need to be more serious. As long as it helps them avoid or lessen disasters, that’s the right approach.
But conversely, if someone is clearly very lucky, and you insist on planting an ‘you can’t do it’ or ‘someone is harming you’ anchor, causing them to become paranoid and upset, that’s creating karma.
Mental anchors can indeed change one’s luck, but it all depends on your original intention and the final outcome—whether you helped them or harmed them.
