Diwali and the Jains

We, members of Shree Jain Sangh celebrated Diwali at the Forest View Centre in Romford, and members of Redbridge Asian Mandal did so at the Orchard Banqueting Suite in Ilford. Hindus celebrate Diwali to commemorate the victory of Lord Rama over the evil king Ravana and other such joyous events by merry making and feasting themselves on sumptuous meals as well as lighting diyas and fireworks.
For Jains, Diwali marks the anniversary of the attainment of moksha by Mahavira (Jainism’s twenty-forth and last Tirthankara or prophet) at the end of his life on earth in 527 BC. It was late in the night of Diwali (Aaso Vad Chaudash) that Mahavira left his earthly body and achieved liberation.
Jains celebrate Diwali in various manners. Some fast for the two days as Mahavira did immediately preceding his liberation. Others join their Hindu friends at parties and generally enjoy themselves.
However, Jainism preaches austerity and observing penances to shed the accumulated karma. I wonder therefore which is the right way for Jains to celebrate Diwali? By fasting as Mahavira did or by enjoying themselves along with their Hindu friends? Jainism also teaches non-violence to even the tiniest living beings.
So I believe that the lighting of fireworks which can harm tiny insects is out of the question for Jains.
