Freedom is important. Freedom from pains, coldness, indigestion, adrenal fatigue, candida etc. This is what I obtained with taking iodine& co.
I have the freedom of choice to take Iodine or other supplements if I like, also the freedom of not taking them.
For me freedom is also not to be dependent on painkillers, thyroid medication, steroids, Antibiotics etc etc.
I am able to excercise, breath consciously, meditate, eath healthily; and more important; I can afford to eath healthily. Because I am relatively healthy and can run out a 20 year old at any time:) Perform my jobs.
What I cant see; is why you propose there is an either or situation at this, where we cant have both.. The spirit works better when the body has all it needs in my experience, like e.g a pineal gland would flourish when rid of its fluoride-calcification. Same as the earth body will flourish when she is in a condition of balanced minerals, less toxins etc.
