In a guided meditation, your meditation session is led by an outside source - whether that’s another person or a recording you made for yourself. Also, there is a specific purpose for a guided meditation. Your goal might be to manifest something like better health, wealth, or deep relaxation (for the purpose of this thread I chose WEALTH).
One of the hallmarks of a good guided meditation sequence is that it's open-ended. A point is reached where the subconscious is allowed to take over and insert its own images and symbols. It doesn't necessarily have to be at the end of the guided meditation. You'll understand what I mean when you read the examples (below). With practice, the images that arise from beneath the conscious mind become interpretable and clear. :)
