Answer

If you mean the first section of Nirayavalika, then chapter 4 is “Krishna.” In the standard chapter list, chapters 3 to 10 follow the same pattern as chapter 1, with only the prince’s name changing. Chapter 4 describes Krishna as one of Shrenik’s sons who joins King Kunik in the Rath-musala battle and dies in that conflict; his rebirth account is given in the same pattern as the other princes.

If you meant the fourth chapter of the Pupphiya section within the broader Nirayavalika anthology, that chapter is the story of Subhadra, who longed for children, became attached to children even after taking Jain vows, and because of that attachment attained the status of the goddess Bahuputrika before a later birth as Soma. ( jainqq.org)

Explanation

The first section of Nirayavalika has ten chapters and is centered on the sons of Emperor Shrenik, with karmic consequences shown through their lives and deaths. ( jainqq.org)

Spiritual Understanding

The teaching is that violence, attachment, and worldly ambition bind the soul. Jain Dharma uses such stories to remind us of the importance of ahimsa, restraint, and detachment. ( jainqq.org)

Takeaway

So, “chapter 4” can mean either Krishna in the first Nirayavalika section, or Subhadra in the Pupphiya section. ( jainqq.org)
