Let’s step back from defining intuition for a moment.
The reason is simple. If you want to build intuition, you need to avoid saddling it with ideas of what it is. When you do so, you are allowing the intellect to shape the intuitive process. These are two independent functions, and they must be allowed to develop independently. Otherwise you end up with basically an older brother speaking for a younger brother. The younger brother never develops his voice as a result, and may even lack a basic self-knowledge of his own desires and preferences.
What you want are two strong, independent forces that learn to work in Harmony. The only way to do that is to keep one from picking on the other or telling it how to behave.
The reason that Taoist practitioners have legendary intuitive skill is because the training process teaches not-doing (wu wei), or not imposing the mind upon the world. A result of this practice is that the intellect becomes restrained and allows intuition to develop. It develops naturally, without the need for elaborate method.
Simple Drill to Create Elbow Room For Intuition
You can also use a basic drill to try to trigger an intuitive moment. Sit quietly. Focus on an issue that you want to gain an intuitive view of. This could be a sudden solution. It could be additional information. It could be a yes or no answer.
Let the issue play in your head, but do not try to solve the issue or think about it. Once you have clearly focused on the issue, do something else. You need to do this other thing to keep the intellect from focusing on the target issue. Personally, I often use cleaning or kung fu to occupy myself.
After a period of time, go back to your quiet time and focus. Many times you will get your sudden intuitive burst at this time. The more your intuition is developed, the more information you will get.
Keep in mind, the more you are focused on your desire, the more likely that your intuitive insight will end up being simple fantasy.
