So about a year ago, I made a post about a Chakra Merging Meditation (Old version, search for 'Redux'). It was effective, but poorly optimized and as a result was more complicated than it needed to be. I recently decided to rewrite it with better instructions and a clearer methodology.
To begin, you must understand that chakras are simply orifices through which your energetic body vents and takes in energies, the ‘pool of colour’ or whatever they are commonly described as is a result of a lack of energetic flow.
To properly begin this exercise, you will start with a basic chakra breathing meditation, where you visualize energy flowing into and out of your seven primary chakras as you breathe. This will open your chakras and make your energetic body more malleable for the main part of this exercise.
Once you have cleared and opened up your chakras, you will fill your body with energy, pulling into each chakra, so the energies pool around each chakra until your body is completely charged. After that, start to push the energies into a circle, so they flow around your body like a hurricane spinning around a central point.
As the energies start to spin and flow, breathe in more energies through your chakras and feed it into the spinning vortex. You will find that you can hold a greater density of energies when they are moving around your body like this, so keep filling yourself up with energies until your entire body is as full as you can possibly get it.
Once you are fully topped up, just let go of the vortex so it spins under it’s own force and stabilizes, as you exhale, feel excess energy flow out from your chakras, and as you inhale, feel more energy flow in. As you breathe, you will vent energies and take in energies.
As a result of this, your energy sensitivity should increase, as well as your ability to channel energies. What ends up happening is instead of having seven distinct pools of energy in different parts of your body, your body becomes something more like a battery crossed with a turbine.
With this meditation, your energetic body becomes stronger and more powerful, just by the nature of the energetic body and astral planes. And after a while, the line between internal energies and external energies will blur, and your ability to manipulate energies will grow to a ridiculous degree.
I finally got around to revising this, and what made me finally get around to it was @Haplo and @Akashiel asking me for it. So thank them for this exercise.
Doing this daily will have profound effects on your perception of energies and your ability to sense, but even doing this once will provide immediate gains. Have fun.
