When God does not respond to your prayers, it is because you are not in earnest. If you offer Him dry imitation prayers, you cannot expect to claim the Heavenly Father’s attention. The only way to reach God through prayer is by persistence, regularity, and depth of earnestness. Cleanse your mind of all negation, such as fear, worry, anger; then fill it with thoughts of love, service, and joyous expectation. In the sanctum of your heart there must be enshrined one power, one joy, one peace – God.
Sri Sri Paramahansa Yogananda
But there is a higher prayer. Much higher.
One where you ask for nothing.
You are silent. You give up all thoughts. Even the thought that there is a body. No worries. If you can do this for a few seconds …. that is samadhi
