In the Fourth Way, knowledge goes hand in hand with verification. Knowledge can be given, but verification is only earned through payment. In this tutorial, we will go deeper into the principle of payment; we will weave it into the non-expression of negative emotions; and view the effort of non-expression of negative emotions as a form of payment. We will draw from the Biblical story of the hospitality of Abraham, a symbolic expression of the need of sacrifice to receive the present on its own terms. And we will see that resisting the expression of negative emotions is a fundamental payment in this work.
