Yes this is true, and for every thought there is an anti-thesis, an opposite bias should always be considered, this is the practice of a balanced individual who is carefully opening the gateway to intelligent infinity.
You have a mispercieved concept that I was referring to negative and positive corresponding to wrong and right. This isnt the case. The positive adept would be perfectly balanced and see all as the creator. Positive and negative are paths we choose so that we can gain spiritual mass, and are able to do work.
