According to Osho, there is no 'voice' of the heart: all voices—urging indulgence or renunciation, sin or virtue—belong to the mind’s ceaseless monologue. The heart is silence and inner emptiness. When every thought and counterthought subsides, a stillness remains; in that spaciousness clarity arises and the Whole can descend beyond all dualities.
The mind talks; the heart is the quiet space that appears when the talking stops.
