Vibhang Gyan or Viparit Gyan in Jain philosophy means wrong, distorted, or inverted knowledge.

Meaning:

• It is a type of false or perverted knowledge.
• In this state, a person sees or knows things in the opposite way from the truth.
• Because of mohaniya karma and wrong perception, the understanding becomes biased, incomplete, or reversed.

In simple words:

A person with Vibhang Gyan may:

• take wrong as right
• take impure as pure
• understand reality in a distorted way

Jain view:

This is not true knowledge like Keval Gyan or even proper valid knowledge. It is a defective form of knowing caused by karmic influence.

Note:

Some Jain texts discuss it as a kind of special wrong knowledge, often associated with misuse or distortion of knowledge powers, and it is always considered undesirable because Jain Dharma values samyak darshan and samyak gyan.

If you want, I can also explain how Vibhang Gyan differs from Mati Gyan, Shrut Gyan, Avadhi Gyan, and Manahparyay Gyan.
