In Jain Dharma, Anantanubandhi karm means the most intense bondage-causing passions that keep the soul tied to samsara and block samyak darshan.

You can identify them by these signs:

• Extreme anger that does not cool down easily
• Very strong ego / pride
• Deep deceit / crookedness
• Intense greed / attachment

These passions are called Anantanubandhi because they bind for a very long time and obstruct right faith.

Main identification signs

A person with Anantanubandhi tendencies will generally:

• reject truth even when clearly shown
• feel heavy hatred or anger quickly
• insist strongly on “I am right”
• act with harshness, stubbornness, or trickery
• remain deeply attached to possessions, status, or desires
• be unable to accept Jain truth with purity of heart

In simple words

If the four passions are present in their very worst form, and they prevent the rise of right faith, then that is the nature of Anantanubandhi karm.

Important point

In Jain teaching, these karmas are not usually identified only by outward behavior. Their real presence is known by the inner state of the soul—whether the soul is completely blocked from samyak darshan by those passions.

If you want, I can also explain:

• the four types of Anantanubandhi karm, or
• the difference between Anantanubandhi, Apratyakhyanavarani, Pratyakhyanavarani, and Sanjvalan kasayas.
