I've had a number of people who have expressed difficulty with being able to get a coherent or useful answer out of their
I Ching castings.
When I help them analyze their casting, it is quite often, certainly more than half the time, that the very first thing that becomes evident to me is that the caster
did not take the time to formulate the ideal question.
This is the most important part of an I Ching casting, in the sense that it is the first thing you must figure out, and forms the ground for everything that comes after!
The nature and quality of your question will fundamentally determine the answer you receive.
The nature of your question speaks to the state of mind you have at the moment of making the casting: part of formulating the right question is not just a matter of the question itself, but of taking the time to contemplate and center yourself, to be in the right state to approach the casting.
So remember, first and foremost, when you are going to cast the I Ching, first give yourself a good while to work out what you want your question to be. Think about what it is you really need to know about the situation you want to cast about, and how you can phrase that in a way that will present you with the right sort of answers you can actually use.
