"There are many paths to the mountaintop, but the view of the stars from the top is the same. Start wherever you are." - I. D. Know
The reason there are so many kinds of meditation, is that there are so many perspectives and viewpoints. Every being has their own trajectory and meditating gradually orients you toward the essential, intrinsic truth that we are all headed to.
So have a practice; don't have a practice. The universe will get there either way, and you will arrive in your own time. But consider an important thing- the experience of life with a wealth of meditation is beautiful and enriching. How is your skepticism fulfilling you?
