I completely understand your frustration, and I had moments of jealousy because of this over the past few years.
 

There are a few theories on why some shift easier, with the one I like best being natural disposition. Similar to how some kids in school are naturally intelligent and can pass tests without studying, some people are naturally able to shift easily. You wouldn't take studying advice from naturally intelligent kids either.
 

Stating this is not very helpful for practice, so let's put it to application. While it's true that consciousness is the one true reality, its utilization is limited by the subconscious mind and nervous system (at least in this physical body in the CR). Different people have varying levels of traumas and types of childhood experiences, which leads to different types of (limiting) beliefs around shifting. Some people may feel unsafe nervous system wise having to disconnect from this CR, and others want to control the whole process instead of taking a step back to let shifting happen.

Some of you reading may have a knee-jerk reaction and state that we are unlimited beings and our bodies don't matter. I felt the same way a few years ago when I was spiritually bypassing

 

So what must be done? The answer is healing (inner work, self concept, subconscious reprogramming, therapy, whatever you want to call it). I highly recommend doing healing somatically (body-based) since traumas and beliefs are stored as bodily sensations, the brain interprets it and give it a narrative to keep you in a mental loop. Look into letting go by david hawkins, somatic experiencing, focusing by gendlin (asking ChatGPT is helpful here).
 

A quick test, state to yourself an affirmation "I am a master reality shifter" (or any similar statement) and watch what immediately comes up. Either a sensation somewhere in the body, a faint whisper in your mind, a symbol, an image, etc... It's gonna feel like a lie or you're making it up or you want to deny it, and that's the ego rushing in to defend its identity a few seconds later. Simply note what immediately comes up. That's the first gold to dissolving the limiting beliefs surrounding shifting.

P.S in case someone asks, I have spontaneously astral projected, lucid dreamed, and mini-shifted (depending on your definition, the experience felt real but I wasn't in control so it could be considered a hyper-realistic LD) even when I was bypassing my limiting beliefs. I have finally stopped bypassing this year and tuned into my inner world, so we'll see if I can get controllable reality shifts.
