Universal Mechanics
In the universe, both physically and spiritually, energy flows following patterns according to the laws of nature. At the smallest level of atomic activity, to the huge streams of attractive and repulsive pulls of the galaxies, there is an intelligent natural law. These laws, collaborating with one another, to manifest the natural experience we can perceive, can be accessed and used with consciousness and Love as a tool.
These laws are called angels, demons, spirits, titans, gods (as in minor gods), concepts, gravity, electromagnetic force, all at different levels of density. An angel does not look like a humanoid with wings, it is a force of the universe without shape or name, but like any type of cosmic force, it triggers a concept into the subconscious mind, so that the human can represent itself the force it is in communication with. This is why all those who have perceived angels see them in mostly the same way, because it is the human ability to transpose the other types of energies as images on the imaginative mind, and makes communication accessible with the contacted energy.
The human mind can perceive any type of spiritual force thru its diaphane, the imagination mirror. Instead of letting the imagination under the control of the mind, it becomes free to reflect the subconscious minds perception of the universal force contacted. This is how we can perceive angels and demons thru our inner eyes.
By actively controlling our imagination to direct us in a voluntary dream, we are triggering a specific contact with our subconscious mind to awaken a channel of communication with an energy stream of the universe. Once we arrive at the contact level, once we successfully opened a channel of communication with the desired concept of the universe, we must become passive and receptive, to let the summoned spirit influence our imagination, so that the answer can be passed back to us in the form of dream or visualization.
For example, in a state of half-meditation, see yourself in a calm plain surrounded by forest. This aspect is active control of your dream, not letting anything disturb your imaginative mind. Add to this visualization a big tree in the middle of the plain, with someone seated at its root. Call this tree the Heart Tree and the person seated the Hearted One. You are still in active control, provoking the events, making the dream with your imagination, and naming the elements yourself, so that the contacted information source is the one you wish. Walk to the Hearted One and great him/her. Now it is very important to become passive, to let the Hearted One answer by him/herself, so that you will not be in control of the answer. Then ask a question to him/her, with your active imagination, and become passive again, letting his answer come by itself to your mind.
Through all the visualizations you do, always keep an active focus at the environment you set in place, so that the spirit/energy/mechanics of the universe that you contact is well established, and the link that you establish remains clear and stable. As you keep the active control of the environment, let the central focus of the scene go as it wishes, letting the spirit/energy/mechanics of the universe transmit through your imagination the answer you asked for. If you keep an active control of the central elements of the experience, you will disturb and pollute the message that is sent to you. Keep the link alive by keeping the elements that made the link possible, but let everything else go like it wants to, leaving more place for information to pass. Practice yourself at listening and observing.
With the visualization of symbols, calling the name of spirits or angels, using colored candles and herbal smells, even while standing up and keeping your eyes opened, you are establishing the link in the same way you would with your imagination. Nonetheless, you must keep a passive and receptive point in your mind so that you are able to perceive the information that would come back from the sprit.
