In Jainism, particularly among the Sthanakvasi sect, the concept of "Agni Sanskar" (fire ritual) as practiced in Vedic or Hindu traditions does not exist. Sthanakvasi Jains do not perform rituals involving fire, such as havans, yajnas, or cremation rites using elaborate fire ceremonies. Their practices are strictly non-idolatrous and avoid all forms of rituals that are associated with the use of fire or external symbols.

Regarding post-death rites, Sthanakvasi Jains typically follow simplicity and adhere to the principles of ahimsa (non-violence) and aparigraha (non-possessiveness). The body is usually cremated, as per general Jain practice, but without Vedic mantras or Agni Sanskar rituals. Instead, the focus is on:

• Prayers and recitation of Jain scriptures (such as Navkar Mantra or other Jain sutras)
• Reflection on the soul and its journey as per Jain philosophy
• Discourses by Jain monks or lay scholars on the impermanence of life and the teachings of Jainism
• Charity and acts of compassion in memory of the deceased, such as donating to the needy or supporting animal welfare

The Sthanakvasi tradition emphasizes internal purity, meditation, and ethical conduct over external rituals. Therefore, if you are seeking information on "Agni Sanskar" in the context of Sthanakvasi Jainism, it is important to note that such a procedure does not align with their practices. Instead, the focus remains on spiritual reflection, non-violence, and remembrance through prayer and good deeds.
