In Jainism, the concept of "Agni Sanskar" (cremation rituals) as commonly practiced in Hindu traditions does not directly apply to the Tirthankaras. According to Jain scriptures, Lord Neminath (the 22nd Tirthankara) attained moksha (liberation) on Girnar hill. Upon attaining moksha, his soul was liberated from the cycle of birth and death, and his body is said to have been consumed by a divine fire (divya-agni) or simply disappeared, as described in Jain texts.

There is no specific mention in Jain scriptures of any individual performing the "Agni Sanskar" or cremation rites for Lord Neminath. In Jain tradition, after a Tirthankara attains nirvana, their physical body is not subjected to ordinary cremation rites by humans; instead, it is believed to be taken care of through divine means.

Therefore, according to Jain beliefs, there was no human who performed the Agni Sanskar of Neminath Bhagwan.
