Richard,
There are many "flavors" of Qigong, and the particular one which Master Lin teaches in the LSC package is that of general healing. So, those who are drawn to this particular course are more interested in healing at their particular stage in life.
I think regardless of the package, meditation is meditation. Superficially, there are many, many different brands of mediation, and some resonate more with certain individuals. But the essence of all of them is the same, and it's up to you to find the one that you're most comfortable practicing. It can be as simple as day-dreaming, or as involved as deeper levels TM or yoga.
Let your intuition guide you, and then you will have already begun "unlocking" your other-than-conscious.
