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.
School has no task more important than to teach strict thought, cautious judgment, and logical conclusions, hence it must pay no attention to what hinders these operations, such as religion, for instance.
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
Never belong to a crowd; Never belong to a nation; Never belong to a religion; Never belong to a race. Belong to the whole existence. Why limit yourself to small things? When the whole is available.
If religion were true, its followers would not try to bludgeon their young into an artificial conformity; but would merely insist on their unbending quest for truth, irrespective of artificial backgrounds or practical consequences.
