What do you do with ripened fruit?
You make use of it.
You eat it, cook something, give it to someone so they can enjoy it. Otherwise, it goes to waste.
If your mind is ripened, if you have confidence and certainty, if you understand the practice and the path, then it is time to put it to use.
Fail to use it now and it could go to waste. Don't make the mistake of holding onto a ripened fruit until it goes bad.
