The Mantra of Light (Japanese: 光明真言), or
kōmyō shingon, is an
important mantra of the Shingon sect of Buddhism, but is not
emphasized in other Vajrayana sects of Buddhism. It is taken from the
Amoghapāśakalparāja-sūtra (Chinese translation Taisho ed.
no. 1092)
and is chanted as follows:

* Sanskrit: Oṃ amogha vairocana mahāmudrā maṇi padma
jvāla
pravarttaya hūṃ
* Japanese: On abogya beiroshanō makabodara mani handoma jimbara
harabaritaya un

The translation of this mantra is Praise be to the unfailing,
all-pervasive illumination of the great mudra (or seal of the Buddha),
the jewel, the lotus, and the radiant light turning (or existing in
our world). It is believed in Shingon Buddhism that if one chants this
mantra without ego, and with sincere devotion and clarity of mind,
Vairocana Buddha will place his seal upon the chanter, thus dispelling
all ignorance and delusion.

The mantra was popularized in medieval Japanese Buddhism by Myōe, as a
counter to the increasingly popular practice of the nembutsu.
Interestingly, both practices were often incorporated by medieval
Buddhists at one time or another. A common practice for the Mantra of
Light was to sprinkle pure sand, blessed with this mantra, on the body
of a deceased person. The belief was that a person who had accumulated
much bad karma, and possible rebirth in Hell would be immediately
freed and allowed a favorable rebirth.
