Hesychasm is a kind of religious way of praying and meditating. It is a tradition that dates back to the Old Testament. People who practice hesychasm try to focus their minds on God and become closer to Him. They do this by repeating a special prayer called the Jesus Prayer. They also spend time in solitude, thinking about God and their relationship with Him. By doing this, they hope to experience peace and joy, and to be lifted up closer to Heaven.
