Audios are provided in the author’s voice for specific programmes of BBB. Listening for adults is a conscious activity performed in their complete wakeful state. They may choose to play audios on loop during nights in deep sleep for subliminal learning. This has to be done in a particular sequence and unit by unit only. For children upto 11 years conscious listening is not the advised method. In such cases, parents must initiate subliminal learning for their children by playing the audios in loops of 5 or 10 when their children are in deep sleep. Guidance is given to parents about the process and the steps involved. Learners may choose to listen to these in the voice of their Spiritual Mentors, Gurus. Using digital reading devices does not support the energy of BBB.
