First, you’ll have to follow the preparation steps outlined here, except that this type of conscious travel is best done on a reclining chair or lying down on the floor (doing it in bed will likely result in you falling asleep… )
Once your mind and body are relaxed, you need to visualize another room in your home as clearly as you can, and in as much detail as possible.
If you’re not a visual person, use your other senses. You can listen to background noises or smell a particular odor that would be present in that room. Do you feel warm or cold?
Achieving Mind Travel
You shouldn’t be remembering what that room is like… You’re truly sending parts of your consciousness into that room to visualize it.
Once you’ve fully visualized it, think of your physical body. Focus on your breathing and allow yourself to return all of your consciousness into your body.
Take a few seconds to relax and lie still.
As soon as you’re ready, open your eyes and write down everything you saw: every detail, smell, color, any item out of place, etc.
With your list in hand, walk to the room and confirm your findings. Did you correctly identify the position of objects or the temperature, smell, etc.? Keep practicing this virtual visit process until you become good at it.
Once you have successfully mind traveled to another room in your home, you can try to mind travel to your friend’s house.
Note: Ethically speaking, you should tell your friend about your attempt to mind travel to her/his house. You should pick an open-minded friend who will understand what you are aiming to accomplish. By telling your friend and getting her/his approval, you won't feel like you're spying on him/her. If you see something that you think your friend would not want you to see, then withdraw immediately.
For example, let’s say that your friend Lucy is open-minded and you trust her. You meet for coffee, and among other things, you mention that you are learning how to astral travel and with her permission, you would like to practice mind travel and visit her tomorrow afternoon.
She agrees and the following afternoon, after going through your preparation steps and visualization, you focus your concentration on Lucy. Perhaps you think about her perfume, her clothes, her hair, her home, whatever is needed to trigger an image. Imagine BEING Lucy, and being in her house.
Suddenly, you see her or you feel like you are her. She may be doing laundry down in her basement.
Try to get as much detail as you can. Can you smell the laundry detergent? Is she doing a dark load? What is she wearing?
Then, focus on your breathing, and think about your body. Allow your consciousness to return to your physical body. Give yourself time to relax and relive the visualization. Then write down specific details about what you saw, heard, felt and/or smelled.
Confirm Your Travel Findings
Call your friend Lucy to confirm your findings. Perhaps you got it right, perhaps your friend was cleaning her house and somehow the scent that you smelled was not laundry detergent but fabric deodorizer that she was spraying on her carpet.
Use her feedback to improve your skills.
If you realize that your visual cues were wrong, but your aromas were right, focus on your sense of smell.
Keep trying and don’t despair. It takes a lot of practice to improve these skills.
Once again, keep in mind that you should not use this ability to spy on people. If at any time you see and/or see things that you were not meant to see or hear, withdraw immediately.
You can also use mind travel to go and explore places you’ve never been to. Museums, foreign places or even the building where you’ll have a meeting or interview next week.
Most importantly, keep practicing mind travel if you want to master astral travel soon.
