In order to live perfectly, you must first use your 'brain' well.
Even if you have a car, you have to know <how to operate the car> in order to drive.
In the same way, you must know <how to operate your brain>.
Then you will be able to live your life properly and perfectly without causing accidents.
Second, in order to live perfectly, you must 'grow'.
That is, your <body must grow, your mind must grow, and your actions must grow>.
