"The hardest obstacle to overcome is yourself. When you sit to meditate at night, your nervousness and restlessness are still with you. Learn to control your mind and body. Be king of yourself. Carry within you a portable heaven, and in life or in death, in heaven or in hades, that inner heaven will be with you.
Pray deeply, sincerely, "O God, I yearn to know You. You must answer me!" and next morning pray again, "Lord, You must come to me!" and pray again the next night in the same way, in the language of your heart; if you keep on, He must respond. But when you pray halfheartedly, while thinking in the back of your mind about something else, He knows He is not first with you, and He does not respond.
Have God first. Have God now. Don't wait, because delusion is very strong. Before you know it, the time will have come for you to quit this world. Whenever you have a moment, sit down and meditate. No matter how many times your prayers have not been answered, don't worry; keep on praying. Pray with sincerity. Believe that your prayer is answered.
I urge you to pray not for little things, but for His presence. Only that prayer is worthwhile
To be able to demonstrate health or wealth or power or friends with God's help is fine, but if you can coax God Himself to respond to your prayers, you are a man of destiny. So don't rest until you demonstrate God in your life. He will give you everything you ever wished for; and He will test you. The tests in the spiritual life are greater than in any other. But you who pass His tests shall say: "Lord, my greatest prayer has been answered. What else could my heart want or need, but You?" "
