It is not a private experience but a public fact. It is an object with which this consciousness has a special relationship, because this brain is connected to this body, rather than to other bodies or external objects. The self is taken to be the subjective realm in contrast to the world of external objects. It is merely a point of view. Spiritual freedom may be cultivated first by understanding clearly what it is.
Worldly freedom is freedom of the ego.
On the contrary, it is liberation from the appetites and fears of the conditioned body-mind which fuel such perceptions. The longing for spiritual freedom does not often arise before there has been a loss of confidence in the strength of one's perceptions and ideas of what is reality and where one is going within it. We do not usually question life until it fails us. Worldly freedom is the power to change one's experience. Spiritual freedom is the complementary power to change one's relationship to it.
