I have the privilege of hosting a church life group in our home. During our most recent meeting, we discussed "meditating on God's word."
Blessed is the one who does not walk in step with the wicked or stand in the way that sinners take or sit in the company of mockers, but whose delight is in the law of the Lord, and who meditates on his law day and night. — Psalm 1:1-2
Many people consider "meditation" to be a practice where one empties their mind in order to bring clarity. That is not at all what the psalmist is speaking about.
