Some vibrational shifts are so big that they’re akin to moving to a new country with a different language.
I feel deeply moved by your comparing vibrational shifts to moving to a new city or country. It helps me have compassion for myself when a certain shift is something that I don't just "easily" do on the side. At the same time the image makes clear that it is something that can be done (people move to new cities or emigrate all the time).
And it makes so much sense that if you allow yourself some time to digest the change, it will be easier than if you spontaneously move from Toronto to Mumbai or Tokyo expecting it will be all easy, and after the initial enthusiasm fades away either start resenting the locals for "being so weird", or yourself for being such a sucker at adapting to life there.
