According to Jain tradition, Queen Chelna (also spelled as Cellaṇa or Cellanā) was the chief queen of King Shrenik (Bimbisara) of Magadha and the mother of Kunika (Ajatashatru). Jain texts mention her as a devout follower of Jainism and a prominent lay disciple of Lord Mahavira.

Regarding her rebirth, Jain scriptures specify that after her death, Queen Chelna was reborn in the heavens as a celestial being (deva) due to her pious life, religious devotion, and adherence to Jain principles. Such a heavenly rebirth is considered a consequence of accumulating punya (merit) through right faith, right knowledge, and right conduct.

However, the specific details about which heaven she was reborn into (for example, Saudharma, Ishana, etc.) are not clearly mentioned in the commonly referenced Jain texts. The broad consensus in Jain narratives is that she attained a favorable rebirth in the heavenly realms as a result of her devotion and virtuous deeds.
