Words are definitely spells. That's why it's called spell-ing.

And, unfortunately, some of the most powerful spells are cast by the white-coated priest/authority figures of the medical system.

I'd like to say at this point that most of them are genuinely doing what they think is best, based on their paradigm of what they've been taught and, as you mentioned, many lives have been saved by modern medicine.

However, the belief systems attached to this have separated us from our natural healing ability. An example of this is that people often get better on the way to the doctors. Just the knowledge that they are going to see the "man with the cure" can ignite their own healing power. What a shame that we aren't taught to access this from an early age.

Wishing the best for your sister Aishlinn.
