The Voice of the Silence is one of the most influential books in theosophical literature. H. P. Blavatsky wrote it in 1889 while in London and may have finalised it during her visit to Fontainebleau. The booklet can be considered a manual for mystics, offering guidance during spiritual awakening. William James called The Voice of the Silence a Musical composition. In mystical writings the call to “hear” or “listen” is “a password to mystical regions,” indicating a shift to a higher state of consciousness. In this manner, very often, an indication the mystic is establishing contact with its high self or soul is often described by the sound of silence, said to be similar to the hissing of a serpent.
