In Jainism, Sallekhana (santhara) is considered a voluntary renunciation and fasting undertaken with full awareness as a spiritual practice. It is not regarded as suicide. Important points:

• It is meant for adults who have the maturity and consent to undertake it, with the understanding of its karmic implications.
• A minor or a young girl would not be considered eligible to undertake santhara. If a young person dies in this manner, the issue is not framed in the same way as voluntary adult santhara; it raises serious concerns about consent, coercion, and guardianship.
• If there were any coercion, pressure, or improper influence by guardians, family, or others, Jain teaching would view that as an improper action on the part of those who induced or pressured the person, rather than as an approved act of santhara itself.
• Ultimately, Jain ethics emphasizes intention (arn) and non-violence. The karmic outcome depends on the seeker’s own awareness and consent; coercion or harm to a vulnerable person would be incompatible with right conduct.

If you’d like, I can share more specific Jain-scriptural references and how different traditions interpret santhara, with careful attention to the stated guidelines.
