Saddhā Included Disprovable Truth, So Kālāmasutta Excluded "Trust In (Real) Rationalist Teacher"

And trust, in kamma+vipāka (causes and effects), is used to prove "the teacher is rationalist". Because people maybe have not enough ability to prove someone, ability, that better than their ability. So disprovable truth, such as the better ability person, is excluded in kālāmasutta.

So when people enlighten as sotāpanna, they must will never have any micchādiṭṭhi, that is wrong causes or wrong effects flavor, any more. And they also have a perfect, unchangable, trust in buddha and saṅghā, who are the real rationalists.
