Meditation - unfortunately too many people have made a living from it, thus the expansion in babble, surrounding the topic.
It is simple - the process aims for complete mental silence or thoughtlessness so that the mind is pushed aside and consciousness allowed to shine through. Takes time and persistence, but you will know you have progressed admirably once your vision sees the environment around you begin to glow. This shows a lifting of the 'veils' - you start to see in many new and interesting ways, unlike before, when hindered by the ego.
