In contrast to silent prayers, have test participants applied audible prayers?
Not too often. If it was someone’s preference, he or she could be verbal. The advantage of silent prayer is its non physical character. There is sufficient evidence that sound and music promote plant growth. The vibrations of moving air that reach an organism prayed for could interfere with the experiment being a clean experiment. During tests the control group organisms were in the same room as the prayed for organisms. If there were extraneous prayers and noises in the room, the control group and prayed for group were affected equally. Silent prayer does not appear to move air in a known way. If a participant were asked to pray from the next room away from the organisms, he or she could pray, meditate, hum, bless, rapp, chant, or talk anything they wanted to about affirming something beneficial toward the organisms. Some participant’s prayers harmed instead of healed the plants.
