I know for myself, I didn’t allow myself to be the divine paintbrush, because I thought that it had to be perfect in order for it to be put into the world.
The divine already knows the perfect expression it would like to express through you. This doesn’t mean that you don’t practice or cultivate your expression. It just means that you have to start putting it out there.
It’s up to the divine to choose the inspiration. Your job is merely to allow yourself to be used to Express that inspiration into the world. Let it bring the light it was meant to don’t worry about the form, instead, be aware of the energy that you are putting into it the content of the expression.
