Many years ago, a Parsi woman studying at a college in Gujarat fell in love with a Muslim professor, Nisar Ahmed, who was 15 years older than her. Despite strong opposition from her family, she chose to marry him.
Even after marriage, she never converted to Islam. She continued to follow and practice her own faith, Zoroastrianism, throughout her life.
When she recently passed away, her husband approached the Parsi community to have her last rites performed according to Zoroastrian traditions. They refused because she had married outside the community.
He then turned to members of his own Muslim community to bury her according to Islamic customs. They refused as well, since she had never converted to Islam.
Left with nowhere to go, he approached the Hindu community. Without asking about her religion, caste, or background, the Vishwa Hindu Parishad (VHP) stepped forward and arranged for her final rites to be performed with dignity according to Hindu traditions.
This is the spirit of Sanatan Dharma.
