Aren't we all both positive and negative polarity?

[loostudent]

There is a turning point, a fulcrum which swings as a mind/body/spirit complex tunes its will to service. If this will and desire is for service to others the corresponding polarity will be activated. (72.7)

The entity, as it becomes more and more conscious of its self, gradually comes to the turning point at which it determines to seek either in service to others or in service to self. (75.23)
