I spent a lot of time with researching minimalism and decluttering ca. 2 years ago when I first got the Ascension tag. It definitely made me to clean up my life. I got rid of more than 1000 items back then (half of it donated and half trashed).
If I find the time to dig into my notes, I will post the best decluttering questions/methods that I have found back then.
So fields wise, I would also recommend everything that (forcefully) raises one’s vibration. As one’s vibration rises, the clutter will become unbearable and one will have no choice but clean up and ugrade. As within, so without. As without, so within.
Also Amygdala Healing, Root Chakra Healing, Soul Core Restoration and The Star Being Experience for healing existential fears.
