A short poem.
We distinguish the announcements of the soul, its manifestations of its own nature, by the term Revelation. These are always attended by the emotion of the sublime. For this communication is an influx of the Divine mind into our mind. It is an ebb of the individual rivulet before the flowing surges of the sea of life.
The world is full of accounts of people who have experienced a heavenly light, and have communed with the divine.
