In Jainism, kaṣāya means the passions that bind the soul with karma.

Main classification of kaṣāya

There are 4 primary kaṣāyas:

1. Krodha — anger
2. Māna — pride / ego
3. Māyā — deceit / illusion / crookedness
4. Lobha — greed / attachment to possession

Sub-classification of each kaṣāya

Each of the four kaṣāyas is classified into 4 degrees of intensity:

1. Anantānubandhī

• The most dangerous form
• Causes strong bondage and prevents right faith
• Very deep and lasting

2. Apratyākhyānāvaraṇa

• Prevents partial renunciation
• Blocks vows of a layperson

3. Pratyākhyānāvaraṇa

• Prevents full renunciation
• Blocks monk-like restraint

4. Sañjvalana

• The mildest form
• Appears even in spiritually advanced beings
• Can still disturb inner purity

Total count

So the full classification is:

• 4 main kaṣāyas
• Each has 4 subtypes

That makes 16 forms of kaṣāya in total.

Traditional note

In Jain scriptures, kaṣāyas are also discussed in relation to:

• No-kaṣāya or secondary passions, such as:

- hāsya (laughter) - rati (liking) - arati (dislike) - bhaya (fear) - śoka (sorrow) - jugupsā (disgust) - puruṣaved / strīved / napuṁsakaved (sexual passions)

These are sometimes listed separately from the four main kaṣāyas.

Simple summary

Kaṣāya = 4 main passions

• anger
• pride
• deceit
• greed

Each has 4 levels

• anantānubandhī
• apratyākhyānāvaraṇa
• pratyākhyānāvaraṇa
• sañjvalana
