Answer

In Digambar Jainism, the three types of knowledge commonly associated with Dev Lok (heavenly beings) are:

1. Mati Jnana — knowledge through the mind and senses
2. Shrut Jnana — knowledge through hearing, study, and scriptural understanding
3. Avadhi Jnana — clairvoyant knowledge of material things beyond the senses

Explanation

1. Mati Jnana

This is ordinary knowledge gained through:

• senses
• memory
• reasoning
• perception of the external world

2. Shrut Jnana

This is knowledge of:

• scriptures
• teachings
• words heard or remembered
• proper understanding of doctrine

3. Avadhi Jnana

This is a special type of knowledge in which a soul can directly know:

• distant objects
• subtle material things
• things hidden from normal senses

In Jain cosmology, devas may possess these knowledges according to their birth and karmic state. They do not have Keval Jnana unless they are fully liberated, and Manahparyaya Jnana is generally associated with advanced human spiritual attainment, not devas.

Spiritual Understanding

In Jain Dharma, even heavenly beings are still within samsara. Their knowledge is greater than that of ordinary beings, but it is still limited.

This teaches that:

• higher realms do not mean liberation
• real freedom comes only through shedding karma
• Keval Jnana is the highest and complete knowledge

Takeaway

So, if you mean the knowledge found in Dev Lok in Digambar Jainism, the three are:

• Mati Jnana
• Shrut Jnana
• Avadhi Jnana
