Resistance to the spiritual search -- in the form of desires, fears, attachments, and so on -- can be dealt with in different ways. It can be dealt with in "non"-spiritual ways, like therapy. It can be dealt with attitudinal changes, like telling yourself that God will take care of everything. But self-inquiry has a different approach to the issue. It simply asks: whose resistance is this? It doesn't directly try to oppose the content of the resistance, doesn't try to argue against it, but merely asks who it is that is aware OF the resistance. That creates a pause and a space that leads to the recognition that these resistances themselves do not belong to the "I" that seems to suffer from them. And this is true not just for spiritual resistances, but indeed for all suffering -- suffering is only a problem if it's "yours," and that's just what self-inquiry questions.
