Prayer is the first Step for Discernment.      
How do I pray?    
  Various forms of prayer are presented in the Catechism of the Catholic Church (CCC 2623-2649). These various forms include prayer of bless or adoration, prayer of petition, prayer of intercession, prayer of thanksgiving, and prayer of praise.    
What is meditation?  
Meditation is a Christian practice of prayer dating back to the early Church. As the Catechism states: “Meditation is above all a quest. The mind seeks to understand the why and how of the Christian life, in order to adhere and respond to what the Lord is asking.” By meditating on the Gospels, holy icons, liturgical texts, spiritual writings, or “the great book of creation,” we come to make our own that which is God’s. “To the extent that we are humble and faithful, we discover in meditation the movements that stir the heart and we are able to discern them. It is a question of acting truthfully in order to come into the light: “Lord, what do you want me to do?” (CCC 27905-2706).

Meditation is an essential form of Christian prayer, especially for those who are seeking to answer the vocational question, “Lord, what do you want me to do?”
