Hello, as you all know Im the newbie, again

I wanted to ask you people that I read about the encylopedia, and thinking of buying a vessel that can open the portal for me so that I can Astral Project. Is only thing I have to do is hold the vessel in my hand in a relaxed position and focused state of mind? Can I do lying down or sitting in Yoga position?
It says that vessels specifically built for No Invocation needed which is really awesome.

So I would like to ask you no matter what the price is, which vessel would you suggest me to buy for Astral Traveling?
What Im seeking is Non-Sleeping Trance which can be like I asked in yoga position, because If its going to happen in my dream, Im scared that I might not do what I want when Im in the realm whilst am sleeping and thinking its a dream

Rather then a vessel do I need to add something to my shopping bag?
I only seek for Astral for now, so that I can prepare my mind to spiritual world, and when doing these read more and more , learn more and more before buying a Jinn.

Thank you.

You don’t need a portal to astral project, however if you feel it might work I say go for it but it should mention what to do be it a ‘activation word’ or process. As for the position it’s whatever you’re comfortable with but not to a point you’ll fall asleep.

Just go with your intuition on what to buy.
