Words and thoughts are the seeds; when repeated often we are fertilizing them and they will grow strong in our minds until they become part of our subconscious, until they become part of us.
For good or bad this pattern of repetition is often done unconsciously; our inner conversation in the end changes our subconscious mind, which then, accepts them as real.
If we let our thoughts connected with fears or anger seize our minds, our behavior and actions will be as negative as our thoughts; our subconscious will accept those thoughts and it would manage to throw obstacles in our way.
On the other hand, if we keep telling ourselves that life is great, there is hope and we are confident about our success, we will find opportunities and entries to take advantage of those opportunities.
This behavior is called the power of affirmation; every thought you think and every word you speak is an affirmation; positive or negative.
Knowing this, if you consciously choose constructive thoughts and words your future will alter creating better situations and circumstances for you. You will improve your life by using the power of affirmation.
So, when we stop our kids from using the word hate, we do it because we believe that hate is a strong word full of ignorance and inflexible thinking; a word that if repeated constantly it will be engraved in their minds and it will become part of their inner beings. They will become intolerant toward those who hold different opinions.
Always remember: the thoughts that you express through your words will condition your mind and your mind is always what creates your reality!
“Your beliefs become your thoughts. Your thoughts become your words. Your words become your actions. Your actions become your habits. Your habits become your values. Your values become your destiny" - Mahatma Gandhi
