What is meant by "deliberateness"?

Deliberate effort is the mind consciousness suppressing the manas, subduing the manas, regulating the manas, perfuming the manas, and guiding the manas; it is leading and admonishing the manas. At this time, the manas has not yet been perfumed and has not developed good habits. Once the manas has been successfully perfumed and has formed good habits, the old ox, having become obedient, will change its stubborn temper. Then the mind consciousness no longer needs to manage, suppress, or subdue the manas, and no longer needs to deliberately do anything; it can simply accord with the manas's good habits and will not transgress the rules.
