Diwali holds significance for both Jains and Hindus. For Jains, it marks Lord Mahavira's nirvana (spiritual enlightenment) at Pavapuri in 527 BCE. For Hindus/Sikhs, Dayanand Saraswati also attained enlightenment on Diwali in 1883. The other pairs are incorrect combinations of ISKCON and Gaudiya Vaishnava figures not associated with Diwali.
