Hi
@JAM2b
Great question.
The Hebrew word for mediate is the same word to describe an animal chewing the cud. If you understand that process, in say a cow, it will help you understand meditation further.
For example, I may meditate on a Psalm for a day, week or month (sometimes year!). I roll the words around my mind and dissect them - like teeth chewing through grass over and over. I think about the meaning and motive behind the words, the choice of words, the thoughts raised, the conclusion (or lack of one), I pictured the environment of the author and his heart, I think of the application for me, I try and equate situations in my life or faith that matches, its importance, its structure, what it
doesn't say, and so on...
But here is the key. Be prepared to say at the end of your ponderings. "I don't know" or "I'm not sure I get it all" at the end of it. Be prepared to come back to chew it over again until you have really digested it fully.
The biggest mistake you can make in your mediations is rushing or assuming you have understood the passage. The goal isn't to understand it. The goal is to live it and experience it spiritually and digest it so it melds with you. Then, in time, the sustenance from that mediation will bring vitality to you as when the need/situation arises.
I hope something in that helps you. And enjoy it! Biblical mediation is a fun pastime and awesome for self-development and even on occasion hearing from the Holy Spirit.
Peace.
