This sounds extremely dangerous. Having low amounts of dopamine or even just a decreasing amount of dopamine can cause psychosis and Parkinson's disease.
Don't listen to this garbage without talking to your doctor first.
Read my original guide: "This is not to demonize dopamine; it’s an important brain chemical, and people who are low in it (whether naturally or by taking antipsychotic medications) can be lethargic and anhedonic (taking little interest of pleasure in things). Also, properly-prescribed dopaminergic medications can help people with ADHD & Parkinson's improve their ability to focus and regulate their behavior. Rather, my point is that we may be getting too much of a good thing, especially when dopamine reinforces behaviors that are out of line with our values."
I think you are taking the title a bit to literally. By "dopamine fast", what is meant is abstaining from activities that give you "cheap" dopamine hits, such as participating in social media and receiving likes in your posts.
This is absolutely safe. If you brain is healthy, it will produce the dopamine it needs either you want it or not. Abstaining from Facebook, or even abstaining from all activity and spending the day staring at a wall will not change that.
'Purity is not goodness, it is having clear and undistorted communication with all our levels of experience.'
'The teaching of purity and simplicity is therefore not an attempt to narrow down our life and experience, it is not a type of punishment, it does not invalidate our individuality neither does it bring special dispensations with it from God. It is nothing more or less than what is understood in scientific terms as a law of condition of nature which we must accept and work with because it is not within our ability to change. To be pure is not to be in fear of making mistakes which will make God angry with us and thus punish us. It is rather to eradicate from our attitudes the hesitations and suspicions which prevent us acting and experiencing with intensity and conviction.'
It isn't necessary to be formally religious to understand that the object of purity is to make the varying intensity of one's responses be truly integrated with the situations that one encounters, whether one is being attacked by a lion, at risk of ostracism, receiving good news, celebrating a birthday, etc.
