the first and second most important doctrines on the list are telling you to first and foremost watch out for those who would manipulate you with bad motives.
Which doctrines are you referring to?
PD01. The blessed and incorruptible nature knows no trouble itself, nor causes trouble to any other, so that it is never constrained by anger or favor. For all such things exist only in the weak. [1]
PD02. Death is nothing to us, for that which is dissolved is without sensation; and that which lacks sensation is nothing to us.
And to add to what Cassius said, more specifically referring to those who are trying to convert people to a religious viewpoint which holds that a God will judge you in the afterlife.
