As you grow in true spiritual power and understanding you will actually find that many outer rules and regulations will become unnecessary; but this will be because you have really risen above them; never, never, because you have fallen below them. This point in your development, where your understanding of Truth enables you to dispense with certain outer props and regulations, is the Spiritual Coming of Age. When you really are no longer spiritually a minor, you will cease to need some of the outer observances that formerly seemed indispensable; but your resulting life will be purer, truer, freer, and less selfish than it was before; and that is the test.
