In Tattvārtha Sūtra, death is understood as the separation of the soul from the body when the lifespan karma is exhausted.

In simple Jain meaning:

• The jīva does not die.
• Only the body ends.
• Death happens when the āyu karma completes its rise and the soul leaves one body to take another.
• So, from the Jain view, death is not the destruction of consciousness, but a transition of the soul according to karma.

A key Jain understanding from Tattvārtha is:

• Bondage continues through karma
• Birth and death are both part of saṁsāra
• Liberation means freedom from this cycle entirely

So, Tattvārtha Sūtra presents death as a karma-driven change of embodiment, not the end of the soul.
