The beauty of the soul comes from the healthy exercise of freedom.
The exercise of Freedom is the possibility of making good choices. We have choices, options: bad, good, better… but the healthy exercise of freedom is choosing the good and the better and that is what makes the soul beautiful. Choosing what is good or better requires knowledge of what is good in itself. It requires knowing the consequences of choosing the good and a high sense of responsibility. Responsibility is the price we pay for freedom. We can choose the bad but it will not be an exercise of freedom, on the contrary, it will be a degrading human act.
Freedom is nothing but a chance to be better. Albert Camus
