The very, very short answer is, the majority of dis-eases occur due to unexpected psychological shocks in our psyche/minds. Which apparently, almost nobody wants to hear. Very rarely, malnutrition (i.e. scurvy, goiter) and poisoning (i.e polio, small pox, and "the jab") can also be causes, but are normally rare in comparison to the big killers such as heart diseases, cancers, lower respiratory diseases, "auto-immune" dis-eases, etc. etc. etc.
Yes, you can extrapolate this to the etheric/spiritual level. Ultimately, a perfectly sound mind equates to perfectly spinning chakras which means no physical maladies are present. But that's a step wayyyy tooo far for most and it's "scientifically" unprovable, so will convince very few. Further, until we become fully spiritually "awake", encountering issues in life that catch us off guard (which cause the vast majority of illnesses) is unavoidable. This is the "scientific" part of explaining illnesses which does resonate with people that are ready and willing to understand this.
You can practice spinning your chakras in your imagination. Lots of guidance can be found out there. I recommend a practice of "witnessing presence" as the simplest and most effective. It's simple ---- but not easy (for most of us).
The idea with witnessing presence is to set aside time to neutrally observe whatever comes up in your thoughts or emotions - the two most powerful "things" in everyone's life. Most of us have certain thoughts and emotions that upset us for a wide variety of reasons, which we simply push back down inside us, repressing and suppressing them. This is effectively what causes "chronic" dis-eases.
The thoughts/emotions are looking for "acceptance/allowance/forgiveness" in order to be released from your being. Until this is accomplished, these thoughts/emotions get stored in various parts of the body. This is why the practice of asanas (stretching) in yoga is so effective as oftentimes the stored thoughts/emotions can be gracefully released without having to neutrally witness them.
Both practices work in the long run. Witnessing presence is the fastest by far but you do have to look at these things neutrally with acceptance that heretofore you unwittingly have treated with disdain/disgust/embarrassment/anger/shame/guilt/etc and haven't been willing to address. The yoga practices can take years and years, even decades of dedicated practice to achieve the same.
The biggest roadblock for most of us in the west is that we've been indoctrinated into a full schedule life of distractions and entertainment that dominates our every waking hour. Your willingness to eliminate said distractions and entertainment, as much as possible, replacing these with silent sitting (aka "mediation") witnessing presence will in short order rearrange your life in such a way as to simply be astonishing to you when you look back on it. I speak from experience.
Lastly, as far as "meditation" goes, you can pick and choose any number of "TECHNIQUES", like following your breath, observing thoughts, focusing on a point in your mind/head (pineal gland), concentrating on a candle flame, etc. All are fine if you feel it's working for you. But you should always be moving toward "NO TECHNIQUE", as "meditation" literally means the art of "being present" --- or said another way "doing nothing", "the art of being". So as long as there's a "technique" involved, you aren't really "meditating". The purpose of the technique is to allow you to slip into meditation, just as you slip into sleeping every night. Both are the same in this regard as both move you out of the blabbering monkey-mind, which is ultimately the source of all our problems.

Ah, physical manifestations of mental conditions, basically. Physical manifestations of unbalanced chakras you think?

I wish I was more balanced!
