  Where differences arise among Mādhyamika thinkers is on the issue of how these two truths relate to one another. Does careful verbalization and thinking do any good in bringing one closer to nirvana, or is it invariably an obstacle? Is there any room within Madhyamaka for clear thinking and carefully wrought argumentation, or are all attempts to arrive at clear thought and rigorous argumentation ultimately delusional and therefore to be abandoned along with more obvious forms of delusion?
