Good question. I find the ET Contact Tool app to be the most effective step by step guide for first timers. Usually the Sirius disclosure webpage has a step by step guide, but I can't find it today!
In a nutshell,
1) Go into a meditative state
2) Without speaking aloud, project thoughts into Space like this one, "We invite all peaceful beings to join us in meditation for open contact or healing earth"
3)Repeat step 2 at various times throughout the entire process.
4)Coherent Thought Sequencing
4a) Using your minds eye, project an image of the milky way into space.
4b) Using your minds eye, zoom into our solar system. Visualize the Sun with it's nine planets.
4c) Zoom into Earth with it's moon
4d) Visualize North America (or ur continent)
4e) keep zooming into your exact location. Try to be as precise as possible and visualize as many geographic indicators as possible.
5) reverse the Coherent Thought Sequencing process all the way back out to the milky way, and all the way back to your precise location.
6) Keep repeating step two during this process.
You can do it anon! We need your help.
