Like a good parent, your Self must give it’s kids values – a wisdom – to live by.
Tell your good child – the Ego – and your rebel child – the Shadow – to check if their thoughts, actions and words are THE MOST LOVING they can possibly be, both for others – even strangers – and for yourself.
This will give the kids a tool to measure their behavior and direction, and they will start making better and better and better choices, day by day.
Remind yourself, no matter what you do, think or say, that it is the most loving choice you can make in this very moment for yourself and for others. In time, this will make the kids choose more and more in line with the path you are intended for. And to true happiness.
All you need is love.
