According to Osho, when a person goes mad, awareness of the self disappears and only past memory remains. From the moment of madness, no new memories form; the person mechanically repeats impressions from before, unable to be touched by the present, thus appearing incoherent. This memory-bound vacuum can resemble a saint’s emptiness, yet differs utterly: madness is brokenness through turmoil, while liberation is choiceless peace without clinging to memory.
Going mad means your awareness turns off, you stop making new memories, and you just replay old ones, so you can’t meet the present.
