Here’s a brief Jain view on the question of a Jain person passing away:

• Jiva (the soul) is eternal. Death is the moment when the body perishes and the soul moves on to its next life based on the karmas it has accumulated.
• The cycle of birth and death (samsara) ends only when all karmas are burnt off, which leads to moksha (liberation) and permanent release from further births.
• The concept of dying with spiritual preparation is called sallekhana (fasting unto renunciation). It is not suicide; it is a voluntary, disciplined practice undertaken with proper guidance to purify karma and hasten liberation. In Jain tradition, sallekhana is regarded as a noble spiritual choice under strict ethical and ritual rules.
• Digambar and Śvetāmbar traditions both acknowledge the possibility of sallekhana, but there are differences in how it is practiced and interpreted in various lineages and communities.
• For laypersons and monks alike, the emphasis remains on reducing karma through right faith, right knowledge, and right conduct to progress toward moksha.

If you were asking about a specific person or a particular context (e.g., a historical event or a modern practice), please share a bit more detail so I can tailor the explanation.
