The essential question to be asked is whether the traditional form one is thinking about does or does not, under present circumstances, actually provide the means for taking a man all the way in the spiritual life or not? In other words, are the formal limits such as to leave an open window looking towards the formless Truth, thus allowing room for the possibility of its immediate or ultimate realization? If the answer is in the affirmative then that form, however degenerate it may have become, must still be admitted to be adequate as regards the essential, which is all that, rigorously speaking, matters; if on the other hand that form, however pure it may have remained as regards its more peripheric aspects, does in fact fail to pass the essential test, then there is nothing further to be said in its favor.
