When bodhisattvas practice the six transcendent perfections, they attract sentient beings and establish them on the bodhisattva levels, releasing them from erroneous views. When the relative truth is taken as the standard, they systematically present the various fruits, but not so in ultimate truth because all things are without arising, without cessation, without affliction and without purification. This reality of emptiness is non-conceptual and indescribable. Owing to emptiness, they do not become fixated on anything at all, and they do not train in anything except emptiness, signlessness and aspirationlessness. In this way they undertake training—realizing the four noble truths, comprehending the twelve links of dependent origination, and refining the causal and fruitional attributes.
