The collection of prayers in this booklet results from a choice made among various prayers dictated to us by the Spirits in different circumstances. They could have dictated others, in other terms, appropriate to certain ideas or specific cases. However, the manner doesn't matter if the thought is the same. The purpose of prayer is to elevate our souls to God. The diversity of formulas should not make any difference between those who believe or disbelieve in their efficacy and even less so amid adherents of Spiritism, as God accepts all prayers if they are sincere.
