The dependent nature is named ultimate naturelessness. The treatise text only contains the word 'absence'; being without an ultimate nature is named 'ultimate naturelessness'. There is also an essence that is the ultimate absence of the conceptually constructed, which is named 'ultimate naturelessness', because it is the object of engagement for subsequently attained wisdom (pṛṣṭhalabdha-jñāna). As it is said that it is subsumed under those four ultimates, the treatise omits it, but in principle it also exists.
