In the past you may have been disappointed that your prayers were not answered. But do not lose faith....God is not a mute unfeeling Being. He is love itself. If you know how to meditate to make contact with Him, He will respond to your loving demands.
The first rule in prayer is to approach God only with legitimate desires. The second is to pray for their fulfilment, not as a beggar, but as a son: "I am Thy child. Thou art my Father. Thou and I are One." When you pray deeply and continuously you will feel a great joy welling up in your heart. Don't be satisfied until that joy manifests; for when you feel that all-satisfying joy in your heart, you will know that God has tuned in your prayer broadcast. Then pray to your Father: "Lord, this is my need. I am willing to work for it; please guide me and help me to have the right thoughts and to do the right things to bring about success. I will use my reason, and work with determination, but guide Thou my reason, will, and activity to the right thing that I should do."
You should pray to God intimately, as His child, which you are. God does not object when you pray from your ego, as a stranger and a beggar, but you will find that your efforts are limited by that consciousness. God does not want you to give up your own will power, which is your divine birthright as His child.
