Tajalli (تجلّي) is an Arabic term meaning “manifestation,” “revelation,” “disclosure,” or “epiphany”.
A manifestation by which something is made clear and unobscured, as the bride is displayed to the husband or the rust is removed from a sword or mirror so that it shines. The tajalli is the unveiling of a spiritual reality in the realm of vision. It is a direct-seeing into the nature of existence, a showing forth of the secrets of the One in the celestial and terrestrial realms. Ibn El-Arabi
