Only astrally project if you are in a stablemood (if you are clouded by negative thoughts and feelings, you will attract negative entities).
Donot astrally project if you are on drugs – this will take you to a lower plane of disorientation and will be less vibrant.
Just in case, ask your guides to protect you (as there can be malevolent beings).
Ideally, only do it if you believe it will be spiritually benefiting (it is not a necessary part of spirituality)rather than a source of entertainment.
If you do it incorrectly, it could lead to sleepparalysis.
You cannot get possessed by malevolent entities, but they can get attached to you.
Always surround yourself with nurturing and higher vibrational energy, and avoid beings with darker/clouded auras as they tend to be less benevolent (but not always – it is just a precaution if you are new to astral projection).
Avoidfear – do not worry that you can die while astrally projecting (as you will not), if your astral body senses danger it will immediately return to your physical body.
When spiritual teachers recommend you to ground yourself, they usually tell you to empower your root chakra. There are multiple practices including meditation, yoga etc, which can do that for sure. What i want to teach you here is just a shift of a perspective in a sense about the same topic.
Grounding means activity which empowers sense of stability and balance. The secret of this is simple. The key to build up the sense of groundedness is working with your own sense of “Order“.
What do i mean by that? By that i mean casual cleaning.
Connect mindfully the idea of grounding with the idea of cleaning and creating more of order around you. Doing dishes by hands, vacuuming, getting new plants for your windows, buying some orgonite pyramids for your bedroom is great, printing new pictures which you like, creating something like an altar with precious objects. Throw out stuff which you have all the time under your nose, you know that you dont need it, notice that you open some boxes in your home once in a year and for no reason. Get rid of them, the willingness to riddance is purifying.
The essence of all this is doing it with gratitude and mindful perspective. Learn to like these activities and give them some more attention than just putting them in-between other events. By this practice and with this awareness you create better aura for your home and therefore your own auric field can expand and resonate.
