In Shwetambar Jain tradition, after the death of a loved one, the family generally follows practices that support ahimsa, simplicity, and detachment.

Common practices include:

• Keep the atmosphere शांत and prayerful
• Recite Navkar Mantra and other Jain prayers
• Remember the qualities of the departed soul with detachment, not with intense attachment
• Avoid unnecessary violence, lavish rituals, or indulgent feasts
• Follow purity and restraint in food and conduct during mourning
• Give charity or support to Jain causes in the name of the departed soul
• Observe fasting or partial restraint if the family wishes and is able
• Visit the Derasar or pray at home for the soul’s progress toward liberation

In Jain understanding, the soul continues its journey according to karma, so the best support is:

• prayer
• equanimity
• punya through charity
• right remembrance without attachment

Some Shwetambar communities may also observe:

• sutak / mourning period customs
• simple meals
• special prayers on the 3rd, 10th, or 12th day, depending on family tradition

The main Jain spirit is: do not increase sorrow through attachment; instead, generate peace, dharma, and detachment.
