Introduction to These Studies About "Meditation"

What is it? (Brief Overview)

Thinking constantly about something, mentally repeating something, etc.
In many ways, this is the opposite of the world's concept of "meditation," which is a by-product of various Eastern religions. There are many "Christianized" versions of this, but each of them focuses on the idea of "emptying" or "quieting" the mind of thoughts, rather than "focusing" the mind on thoughts. The Bible never uses the word "meditation" in this way.
For a more comprehensive look at the Bible's concept of "meditation," see: "What is "meditation" all about? (Definition)"

All people have things that they like to think about, whenever they get the opportunity to do so. Even when an individual is involved in other activities, something will normally be in the back of his mind, waiting to come to the forefront whenever the opportunity exists.
The difference isn't whether or not people meditate (think about things), but what they meditate (think) about.
By the way... We can often learn a lot about someone, by observing what he does with his free time - the time he has the opportunity to choose whatever he wants to do. What we do in our free time is often related to what we think (meditate) about. [See the short article (just a few comments) about: "Free time."]
