The only way of moving towards consensus on the controversial subject of the nature of Nibbāna is by appealing to the sole source of authority common to practically all Buddhists: the Nikāyas/āgamas. In the present paper I will first give an overview of the usage of the term Nibbāna in the Nikāyas. I will then argue that, according to the Nikāyas, Nibbāna cannot be regarded as a self. Next, I will point out that the Nikāyas do not see Nibbāna as a form of consciousness, including such exceptional kinds of consciousness as anidassana viññā?a and appati??hita viññā?a. Nor can Nibbāna be regarded as equivalent to mind, or any particular state of mind. In the final section I aim to show that the most reasonable interpretation of the Nikāyas is that final Nibbāna is no more than the cessation of the five khandhas.
