What is prayer? Body, mind, heart, love

So what is prayer? Prayer is, you can say it verbally. You can say it mentally. In fact, if there is only empty is the best. But if you're going to use the mind then remember, use it to remember the name of God. So mental. Then when a prayer drops into a heart where even the chanting, the prayer comes from a heart to the heart. So then a prayer has become more convenient in the car. Then a prayer deepens into a simple love.
