The practical application of prayer is akin to communicating with a parent; with the notable exception that communicating with earthly parents carries different nuances. The most apparent difference is the predictably irrational behavior of earthly parental units during times of frustration and anger.
If prayer is the process of communicating with God, then an understanding of effective communication is necessary. Pure communication is an exchange of understanding. However, for the purposes of learning, the process starts with seeking to understand the other person. No expectation of reciprocity. In other words, do not expect them to seek your opinions or thoughts.
