There is an assumption out there, particularly by those who produce these kinds of programs, that everyone
. This is NOT the case. Many people are more connected to the world by what they hear or touch or taste, than what they see. It doesn't mean that your subconscious is "broken" if you don't "see" images, it just means that you operate differently in the world.
When you want to "see" something in your minds eye, and perhaps not being visually oriented, begin with bringing up a feeling that would be associated with what you are attempting to "visualize" to get the image stream started. Many who seem to be less visual are actually quite good at it once they realize that they see things so quickly that they're not consciously
aware of seeing them. By getting into the feelings, though, and hanging onto the feeling a bit longer, one can gradually slow those images down enough that they begin to be recognized as such. If you add in all the different modalities together - feel it, smell it, hear it, taste it even - it takes on a greater reality than just being a flat, faded mirage-type image that disappears like smoke with just a glimpse of it.
That's what makes the difference for many people when they are wanting to create better conditions for themselves and told they must be able to "see" it in their mind in order to manifest it. Use ALL of the facilities of your mind - not just your sight - and you'll get there even faster.
