The followers of all religions want to experience an encounter with God in a personal manner. This is particularly true about the Christians. The best way to experience God is the practice of prayer, and especially interior prayer. Interior prayer is the simplest and the most effective way of drawing close to God through praise, adoration and thanksgiving. This kind of prayer brings to them strength, life, light and peace of mind in the midst of their daily life with all its ups and downs. Interior prayer is a heart-to-heart conversation with God. In order to experience this level of God-human relationship, it is necessary that people are taught to understand and welcome what the Holy Spirit does in each individual. Interior prayer is the moment when this divine action takes place in the human soul.
