Kundalini can do this but like we all know it works differently for different people so it cannot be a sure bet. Maybe for you activation of kundalini may open your nonphysical perception when it's at your naval or sacral chakra. This didn't happen for me. I'm sure it definitely allows access to a number of psychic abilities once it reaches the third eye because once activated the kundalini's main task is purification, so once it gets to the third eye it will clear the blockages and open up the perception of your mind's eye. However, I don't think this would be the best way of trying to perceive within. The best way IMO is to just use the phasing model that is described in glorious detail on this beautiful website. Whether my kundalini is activated or not, phasing is the same for me as it is for everyone else. Doesn't happen any quicker or any easier. If there is a kundalini shortcut to the out of body experience I don't know what it is. I'm not really concerned either because phasing is the best option to me. It's practical and it's universal.
By Focus 2 I mean Focus 2 of Frank Kepple's Phasing Model. The experiences/memories of your "Total Self"/"I-There" can be accessed in the Akashic Records of Monroe's Focus 27. This would be Frank Kepple's FoC 3. Because you are a part of your Total Self you can access your memories there as well. However, your personal memories are stored in and can be accessed in FoC 2 of Frank Kepple's Phasing Model where you can relive the experience.
If I were you once out of body in the Astral I would ask for a Helper to guide me to Focus 27. Basically, when you're out of body "in a different world" ask for a Helper to guide you to Focus 27. I don't know if a Helper can help you when you are in your room, so find a way to become conscious of a different world and then try it. I'm sure you're in the Astral when you find yourself in a different world.
