Hi GaiaHeart!
I'm glad to hear you loved the first three lessons in Seeds. Don't be overly concerned with "getting" it all - I still hear/experience things I didn't notice before, even though I have been using the program regularly since it first came out. Though I normally do very well with visualizing, I found the Energy Bodies meditation challenging at first. As the heart is the transition point between the frequencies of the lower energy centers and the higher ones, the shift into the heart energy moves you from the realm of the mind to that of the spirit. Needless to say, this is an incredible paradigm shift!
As you continue to work with the materials, you will gradually shift from a doing/knowing mode to a much deeper level of being. Try to stay expanded and don't worry about "getting" it. Just let it be what it is and be gentle with yourself as you continue the journey!
As Jetay said, if you aren't a visual learner, check in and see what other senses might be coming into play when you do these meditations. I have a friend who hears energy - bells, trumpets and whistles! You might also see if there is some kind of felt sense of the distinctions between the various energies. These may be very subtle at first, so just notice what is there and then move on. With consistency and perseverence I'm sure you will reap wonderful rewards and experiences from Jeddah's meditations.
Lots of love,
Wendy
