The idea of having a sanctuary room is an excellent one and should be helpful. There is great power in having a regular place, time, habit, and manner of approach to God. Nevertheless at times excessive strain and work may render this difficult and even impossible. He then should simply do the best he can and should not worry about the matter. He will probably find that when he can take up his meditation or study again, after a period of enforced neglect, he will be able to do so with renewed zest and with greater inspiration.
