In his second model of the two truths, Mipham presents an authentic truth and an inauthentic truth. Authentic experience is any perception that is in accord with reality ("gnas snang mthun") and perceptions which do not are said to be inauthentic. This differs from the first model because in the first model only emptiness is ultimate while in the second model the ultimate truth is the meditative experience of unitary wisdom. Instead of just being a negation, it includes the subjective content of the cognition of wisdom as well as the objective nature of reality. In this model the ultimate truth is also reality experienced nonconceptually, without duality and reification, which in Dzogchen is termed rigpa, while the relative truth is the conceptual mind ("sems").
