Could you please tell me more about how to open my aura and how to close it?
I appreciate your replies my family.
Here is a little trick to help with this, which is quite easy to do when you have a grasp on feeling and directing energy.
The normal state of an active and empowered aura is one which radiates outwards, at the same time it is open to external energies to attach, there is a two way interaction, external energy can attach to you or even be drawn in and your energy can radiate out. One way to prevent negative energies or undesired energies from flowing in, is to visualize your aura as repelling these unwanted things, such as how hydrophobic coating on a pair of jeans completely repels all water and the jeans remains dry even when completely submerged under water.
Think about the Sun for example, the Sun radiates enormous amounts of energy outwards, and as it does so, the radiation also pushes away anything nearby, called the Solar wind, which is the force of the radiation from the Sun, strong enough to erode a planet to dust if it is too close. Your aura can do the same, your light which shines outwards can keep the outside at bay purely by its force and brightness when sufficiently empowered. Most people have almost non-existent aura's, so an empowered aura easily pushes away anything external from other people without spending energy on it.
Then a way to limit the interaction of your aura with anything external, such as other peoples aura's when in a crowd, or an unpleasant environment (Hospitals are notorious for having very draining energy, as they are places where people suffer and die a lot), is to radiate the energy of your aura inwards towards yourself rather than outwards. Initiate this before you go to such places, and maintain it that way.
Let your aura form a closed loop, where the energy radiates inwards towards yourself and doesn't escape, nor draws in anything unwanted from the outside. The aura wraps around you, either in a small oval around your whole body, or even directly over your skin if you want to visualize it as such, creating its own environment/spiritual atmosphere around yourself that is separated from the outside world and thus doesn't get contaminated by the outside world. This not only helps to retain energy and prevent energy leeching out, it also helps to reduce your presence so you go by unnoticed or don't get bothered much when outside.
Effectively you would be darker and unassuming, while the light inside yourself is not dimmed at all, you retain your full energy and healthy aura.
To help with visualizing the retention of the energy, visualize it as being drawn back in through the extensions of the Shushumna which extend around 30 cm above your head and below your feet when standing, through the centreline of your body. Your energy gets absorbed into your chakra's, radiates through them into the Nadis spread over your body, and out into your aura, from where before radiating outwards it gets captured and drawn in again by the Shushumna which draws it back inside yourself, creating a closed loop.
You can then visualize this energy being drawn in creating a barrier around yourself which protects against external energies, the external energies just slide past without sticking on, like a knife through the wind, the wind will blow past the knife. Reduce the friction to have everything slide/flow past very smoothly, and you find almost no resistance or unpleasant energies sticking on. Regardless of the environment, you yourself remain unblemished. You can visualize this as a skin tight hazmat suit of light.
This helps a lot in reducing unwanted energy in attaching, especially when you go into public settings.
