What are “life lines” or “life tracks” in Reality Transurfing®?

A human life, just like another matter motion, as a chain of cause and effect. An affect in the alternatives space is always situated close to its cause. In the same way, one follows the other, the near lying sectors in the alternatives space assemble into a life line. Scenarios and decorations of the sectors found on the same life line are more or less uniform in their quality. The human life moves evenly along its line until there is an event that introduces a substantial change in the scenario and decorations. 

Then fate takes a turn and crosses over onto a different life line. You are always on the lines, the parameters of which correspond to your thoughts emission. By changing your attitude towards the world, that is your thought image, you cross over onto a different life line that has different alternatives for the development of events on your current life line.
