Joel S. Goldsmith said this quote

“ The safest course for an Infinite Way student to follow is to admit freely that he does not know how to pray, how to go out or come in, or what to pray for, and then open himself in receptivity to that still small Voice which is within, closer than breathing, and let It pray through him, let It utter Its voice, let It have Its way. If you are praying for someone else, let It inform you, let It inform your patient or your student.Do not try to be Omniscience yourself in your praying, because you can be Omniscience only when you are completely absent from the personal sense of self, when you are absent from any knowledge, when you have attained that place of unknowing in which you definitely know that you do not know, and do not even want to know, but are willing and open to receive spiritual wisdom, spiritual guidance, spiritual strength.When you are praying or meditating for someone else, do not try to transfer thoughts to him, do not try to know what is right for him or best for him, but sit in a state of complete receptivity, and then let the Father function as your consciousness. You may not receive any message for your patient or student, but you do not need any. He will receive it, and he will receive it not from you, but from the Source of you. Your consciousness acts only as the instrument of contact, and you yourself may never know what the message is, or even whether any message has been received ”
