Our Sages refer to Prayer as "Service of the Heart". But the heart cannot work properly unless the brain functions to stimulate and control its opera… - Immanuel Jakobovits

Like sacrifices, prayer is intended to change man, not God. Its purpose is to cultivate a contrite heart, to promote feelings of humility and inadequacy in man, whilst encouraging reliance on Divine assistance.

Even if one is familiar with the precise meaning of everything one recites, the act of worship can hardly have any significance at all unless it registers the overall message each part of our prayers is meant to convey.

In all "benedictions", be they expressing plea or thanksgiving, we affirm that God is the "source" of every bounty we enjoy and of every favour we seek.
