Does anyone else get really fucking pissed at people focusing on chemicals like "oxytocin" instead of emotion/love itself?
We're not machines and our emotions are not chemicals. Oh yes, there are chemicals that correspond with the emotions, but the actual emotions are a different and more powerful thing and mental in nature. The experience of the emotion is not the corresponding chemical.
Anyways, download the libraries, ctrl + f "biofeedback", use biofeedback technique with meditation to focus on producing whatever chemicals you want in your body.
You should just do something flushing out your entire energy body with higher emotions, total body orgasm caused just by willing it, kundalini raising, etc. you'll get much better than focusing on oxytocin alone.
