As Westerhoff points out, these arguments are not always explained fully by Nāgārjuna; instead many are quickly outlined or simply referred to very briefly. This is because the main purpose of these texts was to be memorized by students, whereas detailed explanations were left for the commentaries (Westerhoff 2009, 6–7). Therefore, what will be referred to as "Nāgārjuna‘s" thoughts relies heavily on the interpretation found in such commentaries, especially Candrakīrti‘s Madhyamakāvatāra.
