A bridge is the connection from one road to another and the roads are on the same level. However, bridges in multidimensionality are actually on different levels.
Start going on a bridge and somewhere along the bridge, you can step onto the next bridge and so on. It is like climbing a hill but you don't have to land on the other side of the hill on the same road. You can build your timeline for yourself, humanity and Gaia every time much higher than where you started. With the work that we are now doing, you can always step into a higher vibrational level than where you started. In other words, you don't have to follow the rules of reality in the 3D world anymore.
In multidimensionality, two and two are not four anymore. If you start from point A, you don't necessarily have to go to point B. If you are doing this multidimensional work, you may have enough energy and understanding to get to point C which is on a different timeline. This is where you can use a bridge to go to another bridge because now the bridges are connected to themselves rather than being connected to the level of reality where you started.
Hugs and love to all of you,
