A pragmatic approach to how a community lives, prays and works:
The manner of living, praying and working should be suitably adapted everywhere, but especially in mission territories, to the modern physical and psychological circumstances of the members and also, as required by the nature of each institute, to the necessities of the apostolate, the demands of culture, and social and economic circumstances.
According to the same criteria let the manner of governing the institutes also be examined.
Therefore let constitutions, directories, custom books, books of prayers and ceremonies and such like be suitably re-edited and, obsolete laws being suppressed, be adapted to the decrees of this sacred synod.
What the bishops seem to be saying is that everything that is non-essential to the regular workings of a community should be examined, and if necessary, discarded.
