The certainty produced by the ego is product of the system, which uses us as batteries to produce order out of confusion.
Ordo Ab Chao: "A Latin expression, meaning Order out of Chaos. A motto of the Thirty-third Degree" -- Mackey's Encyclopedia of Freemasonry
"The puppetmasters create "dis order" so the people will demand "order". The price of "order" always entails a handing over of control and loss of freedom on the part of the citizenry. Out of "chaos" comes "order" - THEIR order - their new WORLD order." -- http://www.orwelltoday.com/stagedevents.shtml
That kind of personal certainty is a lack of individual sovereignty. And we can notice the truth of that by examining the fear that is produced inside us. Fear that makes us feel like cornered rats.
The solution out of the ego corner is to stay with the confusion and refuse to try to bring order out of it. This prevents loosh drainage and the energy becomes transformed into personal peace and clarity. This requires a lot of change of oneself and it can therefore be useful to listen to spiritual teachers who talk about this, such as Vernon Howard:https://www.youtube.com/watch?v=jtxpgyWfm0M
