Explanation: When the first wisdom of the sixteen moments of the path of vision arises, because the primordial seeds of the remaining fifteen wisdoms increase, they are all called 'attained', for by the power of the initial wisdom they are gathered and held as generative conditions. Since it says 'all', it is clear that the uncontaminated seeds of vision belonging to the formless realm also increase at this time; calling this 'cultivating the formless' is without error in principle.
