In spiritual treatment, prayer is understood as a means to connect and communicate. It is a meditative action that makes one mindful, conscious, and receptive. According to Spiritism and adopted by spiritual treatment, prayers are not necessarily prayed to remove the wrong from us, but turn us away from negative thought which may cause us harm. Prayers in no way prevent the fulfilling of God's laws, nor do they suspend the course of the laws of Nature. They stop us from infringing these laws by guiding the free will.
Commonly, the belief is held that prayers are recommended by all benevolent spirit entities. To renounce this is to ignore the benevolence of God; to reject for oneself His assistance and for others the good that we can do. Prayer is repelled only from the prideful who deposit faith in their own power and merits, believe it is possible to impose themselves upon the will of the eternal Father.
The power of prayer lies in thought and does not depend on words, the place or the moment in which it is proffered. Therefore, it is possible to pray in all places, at any time, alone or with others. The influence of a place or time is only felt according to the circumstances which favour this meditative action.
In Spiritism, the common notion is held that prayer for a discarnate spirit, i.e. person that has passed away, is beneficial for that spirit. Prayer ‘for the deceased’ is a widely established practice and found in almost all Spiritist centres.
Collective prayer has a more powerful effect when all who pray join in for the same constructive thought and envisage the same goal, thus attuning their minds and bundling their mental force. It will do no good for a large number of people to gather for prayer if each one acts in isolation and on their own account. A hundred people can pray selfishly, whereas two or three joined by the same aspirations, praying like true brothers and sisters in Christ, will give more power to their prayer than would the hundred who are not in tune.
