Jainism teaches that karma particles (karma pudgals) attach to the soul (aatma) through various activities and passions. The soul, according to Jain philosophy, is said to pervade the body but has a specific number of "pradesh" (points of extension or space-points).

When you ask "Kaya pradesho ne karma lagta nathi?" (Which pradesh of the body do not attract karma?), according to Jain scriptures, all pradesh of the soul have the potential to attract karma as long as there is ignorance (mithyatva), attachment (raag), aversion (dvesh), and activities (yoga).

However, when a soul attains Keval Gyan (omniscience), it stops attracting new karmas entirely—this state is called "ayoga kevali." At that stage, the soul’s pradesh are completely free from karmic bondage. Until then, in the worldly (samsari) state, all pradesh are subject to karmic influx.

In summary: In the samsari state, there are no specific pradesh that are completely free from karmic attachment. Only in the state of Keval Gyan (omniscience) do all pradesh become free from karma.
