When we keep ourselves busy with everything external and our minds with thoughts about everything external, the intuition is unable to insert itself into our awareness. Even if it whispers to us, we will not realize what is happening. If we continue to ignore it, we may lose the capacity to hear it at all. It is then that we have to retrain ourselves to do so. The practice of meditation is one such way of training our receptivity.
