Biokinesis harmful?

[Whitelotus]

Everytime i come across psi needle* technique for biokinesis, there's a warning message put up about dna being lost and permanent mutations taking place etc. It only seems like a visualisation technique to me. I dont know how visualization from a positive state of mind could turn risky.
Is there something inherently risky about the method? How different is it from usual visualizations n affirmations?
Has anyone tried it?

*The Needle Meathod
This is a meathod that works for minor things, for example, cold does not seem cold, harder to loose stamina, things like that. Meditate for half an hour.Once you have reached a relaxed state, start letting psi flow through you. Create a small needle of energy in your body. Make it very thin and sharp. Now visualise your genes flowing through your body in small tubes. Tell the needle in you mind its purpose and what to change in your genes. Use will power to send the needle of psi peircing in to the gene stream. Its VERY important that you use psi to cover the hole made, otherwise you'll start to loose the character that made you who your are. Once the needle is in, let it form back in to a small mass of psi and drift in your genes untill it dissalves. Warning do this at you own risk. I will not be held responsible for anything.
