To be on earth, is to have an ego and thus pain and suffering is inevitable. We all make and build an ego here and thus we have to UNDO it if we are wanting an solace, purpose or peace. The only way to undo the cause of suffering (ego) is through miracles/forgiveness. Since prayer is the activating agent of miracles/forgiveness/correction... then true prayer must be learned.
Here is the "Song of Prayer" which is an extension of A Course in Miracles. If you wish to learn HOW to pray and to learn more of what prayer IS truly, then this is an excellent and helpful resource.
