Nine in the second place means:
Perseverance brings good fortune.
The premise here is that the gates to success are beginning to open. Resistance gives way and we forge ahead. This is the point at which, only too easily, we become the prey of exuberant self-confidence. This is why the oracle says that perseverance (i.e., perseverance in inner equilibrium, without excessive use of power) brings good fortune.
