To go more deeply into it, Here is a take into freedom of thought from the Plum Village tradition of Buddhism, The Third Mindfulness Training. I just love this and use it as an affirmation every day:
Aware of the suffering brought about when we impose our views on others, we are determined not to force others, even our children, by any means whatsoever-such as authority, threat, money, propaganda or indoctrination-to adopt our views. We are committed to respecting the right of others to be different, to choose what to believe and how to decide. We will however, learned to help others let go of and transform fanaticism and narrowness through loving speech and compassionate dialogue.
