According to Osho, beyond Dynamic Meditation no specific discipline is prescribed; choose any practice as a voluntary, provisional step toward spontaneity. Remain the master—never a slave to methods. Use disciplines to heat the water, then drop them when the inner 'jump' happens. Paths and stages differ for each person; if courage allows, you can even leap directly into spontaneity without any discipline.
Pick any practice that helps you wake up, use it by choice, and let it go once it has done its job—the aim is natural freedom.
