I absolutely cannot see how one can later make up for having failed to go to a good school at the proper time. For this is what distinguishes the hard school as a good school from all others: that much is demanded; and sternly demanded; that the good, even the exceptional, is demanded as the norm; that praise is rare, that indulgence is nonexistent; that blame is apportioned sharply, objectively, without regard for talent or antecedents. What does one learn in a hard school? Obeying and commanding.
Religion is not a fractional thing that can be doled out in fixed weekly or daily measures as one among various subjects in the school syllabus. It is the truth of our complete being, the consciousness of our personal relationship with the infinite.
