Positive vs Negative

The I-Ching compares the Superior Man (Higher Self) and the Inferior Man (Lower Self). In Freudian talk, these concepts also include Super Ego and Id. When we allow ourselves to focus on the Higher Self, stepping back when tendencies of the Lower appear, it is easier to attain a higher vibration. Continuing to do this, allows us to maintain it. Meditation is probably one of the simplest ways to do this.
