Words are nothing more than spoken collections of sounds, or written collections of letters (symbols). Both the sounds and letters are representations of our world - they have no meaning except what we have ascribed to them over time.
If you know me and my work, you know that I keenly sense the energy behind the words I read and write. This energy IS the meaning. We speak or write with intent to communicate a thought, idea, emotion.
The old childhood saying, "sticks and stones may break my bones..." is a falsehood. Bones heal, but words can cause lasting and great harm when the intent - the energy - is based in force, anger, fear, or any other "negative" emotion.
And words can be a healing balm when the intent is based in love and kindness.
Want an example? Easy - look at any social media post.
That post is a digitally rendered and delivered collection of symbols which represent the intent - again, the energy - of the writer. If the writer portrays himself/herself as a kind, loving soul, but posts divisive, angry, or hateful thoughts, then the writing is inauthentic. It is incendiary. The reader engaging with that post will take on a degree of the expressed emotion - they sense the anger, whether they're aware of it or not, and that energy may stay with them for some time.
This is the power of words in any format...a blog post, social media post, article, book, poem...to harm or heal, to educate or influence, to create love or fear.
Use them wisely.
