Are They Prayers or Simply Thoughts?

In our modern, fast-paced world, the distinction between prayer and thought can often become blurred. 

For Catholics, prayer is a profound and personal connection with God, a vital component of our spiritual life. 

Yet, in everyday conversations, phrases like "I'll keep you in my thoughts" or "I'm sending positive thoughts" have become commonplace. 

This raises a crucial question: 

Are these expressions a form of prayer, or are they merely thoughtful sentiments?
