The I Ching is an intuitive tool that always points to growth and personal empowerment. Using the I Ching is justified every time there is a legitimate need for guidance, insight,
creativity, wisdom, or prediction.
The more thought is put into a question, the more insights will be revealed in the response. And knowing that many possible questions have an answer tends to make one’s mind more curious, inquisitive, and open to possibilities. So an appropriate use of the I Ching does not replace thinking but actually stimulates it, and then transcends it.
However, having selfish motives, asking frivolous questions, doing excessive or unnecessary readings about a subject, ignoring difficult or unfavorable responses, or knowingly avoiding essential questions are misuses of the I Ching that may result in irrelevant responses.
In conclusion, as with any language, practice is necessary to develop a “feel” for the answers and their nuances and make sense of apparently incomprehensible responses. In fact, The Logic of Chance could not have been written without the experience gained from innumerable I Ching readings.
