There are many people interested or experiencing astral projection. The astral does not always mean "Out Of Body Experience". The astral is a mimick plane of the physical plane, yet, it is the purely mentalized, or consciously activated plane, hence, astral. One way to astral project is to take in sensory information about your environment.
Your aura, it's health, and personal energy are important to astral projection. It is 'projection', not absorbing astral energy from others, not reflecting negative energy or even banishing, though, banishing leads to a very specific location in the entire dimensional structure. You build your aura by feeding on reality, this, in turn, generates brain material as you link or unify the experience of sensory information.
True enough though, the chakra are important to building an aura. Yet, you do not generate so called 'chakra energy' by drawing on the external reality. You have to literally emanate the psychic energy from the inside out! A laborious task for those who's consciousness is continually the object of psychic vampirism. It can be done!
As you build your aura in meditation, I will again make mention of the ability to "Sense Reality". This does not immediately jump to and rip apart external reality far beyond your primary sense organs. Rather, as you use your sense organs, and gain greater psychic awareness of your own body, this naturally develops the chakra and will eventually produce full, whole materia. (more on materia later, for now, research "Final Fantasy 7" for info related to what materia is) You do not gain full awareness of anything until you have gained awareness of your own soul. The soul here conveyed as 'the body/mind balance'.
People everywhere are being told utter excrement about everything. Yes, I am Chad Ascher, I am trying to fix the problem but they just keep creating problems. It is a very sad state. Some people are told to shoot all their up into the sky, believing and being told that this will reconnect them to their higher self. Some are told to shoot all their energy down into the Planet itself. Some do say to 'ground' before you 'channel', which is fair. All this talk about shooting energy anywhere is bogus, and should be avoided. That sort of thing rarely is useful, and has little benefit except in 'sith type attacks', for those who know Star Wars and what can be done with an electrical discharge.
Your aura grows from being aware of reality. Moreso, in the beginning and all the way through, your aura grows directly from the amount of energy you are generating in your chakra. The chakra are like 'energy batteries', a battery similar to what you put in your tv remote, yet of a completely different type. This is why some people are targetted and made obsolete in society, so that others can attach themselves to that soul and feed continuously. I will say, it is better to never feed from any other soul, as this is vampirism/parasite bovine excrement. Pure bovine excrement. What sense does it make when you can generate an infinite amount of energy for yourself by using your own chakra? No sense at all. And to think, they make it seem like it has class. They are nothing but waste and parasites.
So if you are going to look into astral projection, the first thing you do is meditate on self awareness. When you have gained complete self awareness, yes, you will be able to shapeshift, grow big cumming balls or tighten that butt, expand those breasts, grow long hair, maintain physical features. I think? you can gain "Zen State". Zen being complete and whole self awareness that never deteriorates and is defended with the greatest ease. It also means longevity and the ability to heal to any 'age condition' you so desire.
As you build your chakra up and grow your materia, and yes, materia is a real, physical energy basis, the very energy of your self awareness, then, you can expand your aura. Astral projection is extremely easy when you have already achieved Zen, then all that is required is the simple action of projecting.
I will make mention here, the main reason that I can no longer phantasy and sustain my realm, is due to the mind control and psychic vampirism. They have drained my realm completely dry, yet! There is a hidden faucet to the reality based in 'faith practices', of which they are not entirely sure exists. Phantasy is not astral projection, yet, at the same time, it is the generation of a 'realm', which takes root in your own internal space. So you have to protect yourself from psychic vampirism.
There are seven chakra.
If you have been depleted, you must regenerate your energy in meditation, and gain Zen State.
When you have gained Zen State, increase your aura with increase of personal energy. This is "Soul Power". In truth, you are only able to access the astral plane that has formed in the trace line grid of your own aura.
When you gain a full aura, and have mastered the astral plane, you will then be able to phantasy and construct your own 'mental realm'.
Beyond these things, I can not say. Only that you eventually gain the ability to manifest material objects, levitate, regenerate yourself and others, and become like Christ.
