In this video, Elizabeth April discusses the purpose of life and the nature of existence across different dimensions. They explain that each dimension represents a different vibrational density, and as souls, we have multiple incarnations in each dimension to learn specific lessons. Once we have learned all the lessons in a dimension, we move on to the next. The ultimate goal is to ascend through all 12 dimensions and become enlightened. At that point, one can choose to either assist others in their journey or become their own source and create their own universe.
