Since ancient times it has been known that your word is a cause set in motion. In fact, the universe itself is claimed to have emanated from a single primordial sound. In the science of yoga, it is believed that certain Sanskrit words, known as mantras, can bring about magical results, thus you can secure abundance with a certain mantra, peace with another, and so on. On a more practical level, your word still remains highly potent. With your words, you can wound someone, sending them into spirals of defeat, and with your words you can heal someone, raising them up from a dismal place to soaring hope and motivation. In fact, the entire field of self-improvement is the transmission of words that will assist others to get a firm perspective and move forward with their lives, fulfilling their dreams and desires. On a personal level, too, your words affect you. What you say to yourself about anyone or anything affects you, too. If you speak well of someone or something, you bring more of that harmony into your life. And if you speak ill of someone or something, you bring more of that frustration and anger and conflict into your life. Psychological literature often speaks of numerous cases where a parent’s words, spoken casually, can affect the destiny of a child. And the most potent words that a parent can use to affect a child are those spoken at-the time of dying since these are the last words, and the moment is so highly-charged and the awareness so acute, these words become an imperative that the child now feels obligated to never disown. Words are further charged with the emotion behind them. The stronger the emotion, the more highly charged the words. Many a love affair has fallen by the wayside because of emotionally charged words, which are later regretted. Despite all this, people use words with the utmost casualness. People wreck their own lives and that of others through the careless use of words. They also accept the words of others as a given truth, when, in fact, all comments by others are merely opinion. Words are causes set in motion. They are reality-creators. The most marvelous aspect of words is how they can bend time. The brilliantly crafted words of Shakespeare or the eloquence of Martin Luther King still shape our lives. Words are so sacred that whole buildings are used to archive them and make them available for reading. A person can rise from poverty to wealth, from sickness to health, and from loneliness to loving companionship simply through exposing themselves to the most beneficial stream of words. Words not only steal hearts, but shape reality as well. The earth can be a better place because of your choice of words. You can fill lives with the miracles of your words. You can be an agent for positive change and bring out the best in yourself and others simply by how you use words. Words are psychic shape-shifters, use them wisely. It can be concluded from the passage that great words ______.
A. may be less influential as time passes by
B. may improve people’s life
C. can change the world
D. can change time
