if you want to experience what he meant
saying- 24; inner light.
He said to them,
Whoever has ears, let him hear.
There is light within a man of light,
and he (or "it") lights up the whole world.
If he (or "it") does not shine,
he (or "it") is darkness.
One who found the kingdom is not only an example to others, but the world as
a whole benefits from the fact that someone realized the kingdom.
Buddhism also sees an enlightened one as a benefit to the world at large.
Without enlightened teachers the world remains in dark poverty. Hedrick (2010) also considers
it possible that "an illuminated person" is the subject.
Such interpretation is understandable if one realizes a non-dual perception about man and the world
around him – fundamentally, they are one and the same.
Obviously, Jesus is one who experienced the light he was talking about, and pointed others
in the same direction. In Buddhist terms he was like "a finger pointing at the moon", but man
made him into the moon itself; Jesus showed "the Way", but man made him into the Way itself.
The saying should not be taken as imposing a missionary assignment, and neither as
a "gnostic" inclination. Meyer points out that the Greek word phōs, can mean human being
as well as light, which sometimes invited to a play of words in Greek literature (Meyer,1992).
Therefore, this could just well be the case here.
According to Quispel (2004), Jesus taught "interiorisation",
as he himself became an enlightened one
at the moment of his baptize - phōtismos - by John the Baptist.
(although there are reasons to remain skeptical about the veracity of such event.......)
