So what is the spirit world like? Is this astral projection, out of body experiences or lucid dreaming? How did you get cred in the spirit world if you were new to it? What sort of work is done in the spirit world?
I take this as genuine inquiry.
Its not astral projection or OBE or lucid dreaming.
Basically what you do, at least what works for me, it sitting or lying down comfortably and getting in a meditative mood, eyes closed, no music. From the platform of having reached within, your mind at inner ease, you start augmenting your reception of sensory input.
What you do is
listen very hard when there is nothing to hear and seeing very vividly with closed eyes. So to say, dial up the microphone's sensitivity. For me it works best with hearing.
When you do this, trying your utmost best to hear beyond hearing etc, you are, just like with sensory deprivation tanks and dissociatives, creating a surplus in
sensory receptive bandwidth and therefore,
an information vacuum.
There is more capacity to hear/see than there are things to hear and see. This presents a problem for your brain, which it solves by filling the void with Meaning. This is standard fare for sensory deprivation tanks and dissociatives, but you do something more.
In this rift between the worlds that you created you start calling out to your allied spirits, and they will answer you and if you have such contracts with them, will pull you into the spirit world as an active participant.
A very good spirit to contact first is that of your heart. Each subdivision of everything has a spirit assigned to it that comprises it, and you can reason with them. The heart is a great place to start as your primary ally because of its devotion to your continued existence and the fact that it is internal, not external, so harder for an imposter to get inbetween. Your subconscious is another great one.
How you get cred in the spirit world?
DO THINGS FOR SPIRITS.
After establishing you both come in peace, your first question should be: "What can I do or you?"
The Universe works with honest weights and measures.
If you do a spirit a favor, they are in debt with you, and vice versa.
The spirits ABHOR!!! the human "slash and burn" mentality of exploiting the crap out of everything. Its why many spirits steer clear of humans. Show that you are not about that, that you come to give and receive in proper measure, and give first.
By the fruits you will know the tree. Benevolent spirits ask small, easy favors and offer trifles in return, and gradually over years both of you build it up.
Some things they ask may even be utterly absurd and of no apparent utility - the purpose then is to see whether you are willing to oblige an absurd request.
Sinister spirits will ask for things you just know aren't right, such as cut an obituary out of the newspaper, drip a drop of your blood on it and burn it. You know it when you see it. When it feels wrong, don't!
You build up cred with spirits. Spirits inform friends that they found a liaison in the physical world willing to transact and contract, this will lead to increasing activity around you.
Your reality bubble changes. Miraculous activity exists throughout, but it becomes increasingly consciously possible around you. The laws of physics become more negotiable, as reality itself is a spirit which can be cooperatively accomodating.
Its a beautiful adventure.
You don't NEED drugs, because you can induce an information vacuum sober without any purchases of powders or gear, but everything that induces an information vacuum (serotonin-psychedelics like LSD, glutamate/GABA-dissociatives like ketamine or propofol, choline-deliriants like datura, kappa opioids like salvia) can be used as a springboard to from there on out, contact the spirits.
Its best that you also learn how to do it sober, so that you can do it at the drop of a hat, in the back of the bus. You can't get high as often as you'd want to enter the Spirit World.
But auditively, picture this:
You listen to the sounds behind the sounds, you listen HARD. Then typically tinnitus starts appearing, then if you persist through that the tinnitus becomes meaningful communication, and then, you're there.
You can have 1000 trips on 1000 micrograms, but unless you start working with the spirits, it stays just tripping.
Running shoes do not make you run a marathon: Its what you do wth them that counts.
