How necessary is it to mind map to build comprehension?.........Is it necessary to mind map at all?
You have accountant up there in your profile. I sorta think an accountant might not take to MMing right off. Figure this: Why would LS put 1 main technique in their whole mind system if it was not in some way worthwhile?
I think b/c of your occupation, you probably are doing more outlining and traditional note taking. If you were actually MMing, as it is meant to be done, you'd not feel it to be heavy & obscure.
Try this exercise to loosen up: Draw a symbol that represents yourself in the middle of a piece of paper...11X17...sideways. Then just start MMing out who you are. Husband, worker, son, your likes, your hopes, your abilities, what you would do if you had no responsibilities, what you would like to change, etc. Just let it flow. Choose significant words and use color. Layer it...meaning, come back to it. Redo it if you want. Make sure it does not look like any kind of linear notes you have ever seen before. enjoy yourself and adventure
YOu know, you can even think in a MM way. I do, so i know it's possible. It can help you with problem solving to memory.
If i sound like i'm trying to talk you into MMing, well, then you are right, i am 
As mgrego2 said--- It definitely helps with activation ---it really does; it's on the books!
