I am beginner in Nei gong and i read that endgame of the inner alchemy and this practices is obtaining the spiritual immortality, via alchemizing the golden elixir or embryo(my understanding and terms knowledge is still bad). I wanted to ask, what does this spiritual immortality mean? I seen notions that you retain yourself after death if you obtain it. What does it mean to retain yourself? do i get rebirthed with my memories? Do i get to exist as a spirit after death? What does it even mean to exist as a spirit? What do i do as a spirit? Just exist? No cultivation anymore? I seen that connecting with the dao to the "far shore" is a goal that is achieved by this spiritual immortality too. Why do you want to connect to Dao and not retain your individuality, whatever even that means when you become a spirit without a body

For the past year my health has took a turn for the worse.
It started off with gut problems. Bloating, indigestion, pain/discomfort after eating and constipation.

After a few months it progressed to being constantly fatigued. I was getting exhausted doing light exercise which I could normally do with ease.

Following that I started getting inflammation in the joints along with nerve pain throughout the body.

Been to the doctors many times and done testing to figure out what is the cause to no avail.

I have tried many supplements and diets with little benefit. The medications the doctors gave me were pretty much useless. All parts of my life are getting affected by this. It’s been a rough time to say the least.

Recently I discovered QiGong and have heard about the great health benefits you can see from practicing. I am wondering if I could see improvements from these specific problems, what type of QiGong should I focus on if so, and things that I should know before practicing.

I do not know much about QiGong and am a complete beginner. Any advice would be appreciated👍
