The text “The Law of One” (the Ra material) goes into detail about this process. That text can be hard to read and Youtuber Aaron Abke has a very good introduction to this text.
During each step of this process of evolution of consciousness, you soul has free will. Your soul decides when and where to be born and to which parents. Every single Earthling has chosen to be born on Earth. And souls are free to leave whenever they choose — it is easy for a soul to set up a situation where the person transitions (“dies”). Then they can rest for a time and start another life.
Thus, you can think of your soul as the director of your personal movie. What you think of as your life, is the movie that this director is currently producing.
Directors don’t have complete control — actors are independent people who can make their own choices to an extent, and if a director wants to shoot a genuine desert scene but there are no deserts nearby then tough luck. But directors — your souls — do have a large amount of control over your lives. And of course, your souls are part of you and want the best for you.
In general, it is beneficial if the movie (what you think of as you) doesn’t try to fight against the director (what you think of as your soul). In fact, if you can learn to directly communicate with your soul by simply thinking “soul, what should I do today” then that’s awesome. If you can’t do that yet, joy and intuition comes from your soul too, so following that is a good idea too.
