Between Concentration and Meditation, there is border-area which covers both and that is the area of Contemplation. To be in that area of Contemplation is to free yourself of worldly attachments. If you break away all the worldly attachments - all the routine attachments in the world - then you enter the region of Contemplation. When you have completely broken away all your attachments, you break through this area of Contemplation and you get into the area of Meditation.
