One magickal principle suggests that words are powerful. Words create worlds, our chants, our spoken spells, and our prayers are an aspect of that.
But the power of words go beyond the times when we deliberately create change. The carelessly uttered words about another, a group of people and also about ourselves are just as important, specifically if they are repeated often.
Examining how you speak about yourself is an essential part of spiritual growth. Do you speak ill of yourself, do you put yourself down on a regular basis or do your words empower you? Becoming first aware and then moving to adjust your uttering just be a priority. Those words spoken in automatic terms are often an indicator of your inner well being, and therefore an important indicator to you what you need to work on.
So think beyond just the times what you say when you are in front of your altar or in conversation with others, but consider how you speak about yourself to yourself.
