In Jain philosophy, Upyog means the active use or focus of the soul’s consciousness. “12 Upyog” is a way of classifying this consciousness into 12 types:

They are grouped as:

• 5 types of Jñān (knowledge – सही ज्ञान)
• 3 types of Ajñān (wrong/false knowledge – मिथ्या ज्ञान)
• 4 types of Darshan (perception – दर्शन)

1–5: Five Jñān Upyog (Right Knowledge)

1. Mati Jñān

Knowledge through senses and mind (seeing, hearing, thinking etc.).

1. Śrut Jñān

Knowledge through scripture, listening, studying, teaching.

1. Avadhi Jñān

Limited clairvoyant knowledge – knowing things beyond senses, but within a limit (distance / area / time).

1. Manahparyāya Jñān

Knowledge of others’ thoughts (telepathic), possible only in very high spiritual stages.

1. Keval Jñān

Perfect, infinite knowledge of all substances in all modes – the knowledge of an Arihant / Siddha.

6–8: Three Ajñān Upyog (Wrong Knowledge)

1. Mati Ajñān

Wrong or confused knowledge through senses/mind – e.g. misunderstanding what is seen/heard.

1. Śrut Ajñān

Wrong or misleading scriptural/second-hand knowledge – e.g. misunderstanding, misinterpretation, or false teachings.

1. Avadhi Ajñān (or Vibhanga Jñān)

Distorted or wrong clairvoyant-type knowledge.

9–12: Four Darshan Upyog (Perception)

1. Chakshu Darshan

Perception through eyes (seeing form/color etc.).

1. Achakshu Darshan

Perception through other senses (hearing, smell, taste, touch).

1. Avadhi Darshan

Clairvoyant perception – direct non-sensory perception of objects beyond normal range.

1. Keval Darshan

Perfect, infinite perception of all realities (goes together with Keval Jñān).

Note on Traditions

• Both Śvetāmbara and Digambara accept these basic 12 Upyog in meaning and spirit.
• Minor differences, if any, are only in detailed technical descriptions, not in the basic list given above.
