Would recommend Dr Lams book The Way of Energy and Moontagu's video on The Complete Basics of Bagua to give you some extra information to help. In the video he goes into really good detail about how to position yourself, which helped me as I had no mentor.
Good luck with your exercises :) and reach out if you need help!
I have an unusual recommendation: practice standing meditation, aka "zhan zhuang." Get the book The Way of Energy by Master Lam Kam-Chuen and practice for 5-20 minutes before work standing still in the way he describes. The goal is to be as relaxed as possible while remaining upright. This is the basis of Qi Gong and Tai Chi, and after a few weeks or months it becomes very relaxing to stand still for long periods of time without pain or discomfort.
Basically you end up training your postural muscles to take over, and to relax all needless tension.
I agree with everything u/DrShevek said. I think it would be best to find a good tai chi or qigong instructor to work with. I haven't been able to find many helpful how-to guides online, and energy work seems to be more of an art than a science in a lot of ways. I personally don't have much money to spare, so I've been using the free Zhan Zhuang videos DrShevek mentioned. Before my first sit of the day, I'll do a few minutes of the warm-up exercise, 5-10 minutes of the posture, and a couple minutes of the cool-down exercise. I feel like it's helping so far!
As I mentioned in response to another comment, I've also been practicing ashtanga yoga for a while now. I don't see as much of a correlation between my yoga practice and these energetic phenomena, but I've also been practicing ashtanga since I was in stage 4, so maybe the energy stuff I'm dealing with now would be a lot worse if I hadn't haha. Ashtanga in particular seems to have a pretty steep learning curve wherein you're just trying not to pass out and/or fall over before you can actually "flow" through the poses with your breath, which is the main goal of the practice. I've gotten a lot better at this over the past couple of months, and have felt some energetic stuff happening during my practice and more relaxation/groundedness after my practice during this time. But I'm not sure if this is an effect of the yoga itself, or just my increased perception leading to me noticing what has been happening all along.
In terms of books, here is the book written by the gentleman who made the Zhan Zhuang videos. I've heard good things about it. I've also seen Energy Work recommended quite a few times.
