528hz is the frequency of your Heart and its magnetic field. You can raise this frequency by focusing your attention on the Heart Center. In meditation, breathing in and out with your focus on the Heart. Seeing the Heart Center blossom like a white rose, its magnetic field expanding. In the Fifth Dimension your Heart’s magnetic field will expand to over three hundred feet in every direction. ~Kejraj

528 hz is one of the solfeggio frequencies.
