There are three ways of prayer according to Catechism of the Catholic Church.

1. Vocal prayer 口祷
2. Meditation 默想（运用思维、想像、情感、渴望）
3. Contemplation 心祷

What is the difference between meditation and contemplation? The following part is a summary from here.

Contemplative prayer is more passive or sublime experience of God. Meditative prayer is more from our work of seeking God (though with the aid from God). Contemplative prayer can be distinguished as the pure work from God.
