It is simple—one person at a time. One person makes a choice in each moment for the upward current and soon that becomes the common way of living in our mind, our feelings, and actions. This becomes so normal that we don’t notice the change and just move forward and upward continuously. This is what transforms our experience of Life. This is the reality of what we are---Ascendant Beings capable of living from Self Awareness. According to MSI, you can have this as fast or as slow as you choose, and the Ascension Attitudes help speed it up.
Whether you want to learn Ascension or not, there is valuable information in this book to help you expand your Self awareness and keep moving upward. It is worth a look and a read.
