Thank-you, bodhimind, for bringing to our attention a sutta that indeed does seem to discuss the visual charism. Here is a link to another translation of
MN-128, where the term in question is translated as "knowledge and vision."
The same topic is discussed in another sutta, below"
Mahaasaccaka sutta (MN 36)
Aggivessana, then it occurred to me, what if I practiced stopping the in-breaths and the out-breaths?… air entering through the ears made much noise. It was like the sound that came from the bellows of the smithy… a lot of air disturbed the top of my head. Like a strong man was carving the top of my head with a sharp blade… I felt a lot of pain in the head...Like a strong man giving a head wrap with a strong turban… I felt a lot of pain in the stomach. As though a clever butcher or his apprentice was carving the stomach with a butcher’s knife… I felt a lot of burning in the body. Like a strong man taking a weaker one, by his hands and feet was burning and scorching him in a pit of burning charcoal… My effort was aroused repeatedly, unconfused mindfulness established, the body was not appeased owing to the difficult exertion. Aggivessana, even then these arisen unpleasant feelings did not take hold of my mind and settle.
