Yes — in Jainism, attachment (rāg / moha) is a major cause of karmic bondage.

In Jain philosophy:

• Attachment binds the soul to karmas.
• It creates asrava (influx of karma) and leads to bandha (bondage).
• Along with aversion (dveṣa), attachment keeps the soul trapped in संसार.

So the short answer is: yes, attachment is karmic bondage in Jain understanding.

But more precisely, attachment is not the soul itself — it is a defilement of the soul’s pure nature that causes bondage.
