Dev Diwali is
celebrated on Kartik Sud(Bright Half) 15- Purnima i.e on the full moon
day. On this day, the diyas are lit under the moonlit sky and the
family celebrates the end of the Diwali fortnight. Also it signifies
the day when we eradicate our inner demons- our inner instincts of ego,
anger, lust, greed etc and thus feel the manifestation of God within
to The Ramayas, after leaving King Bali, the Lord rejoined the devas on
this day. Devas celebrated His arrival in jubilation and thus Dev
Diwali came into being.
Kartik Purnima, Hindus also celebrate the Matsya or fish Incarnation of
Lord Vishnu. According to the Puranas, Vishnu took the form of a
gigantic fish to save Manu, the father of the human race. Manu saved
all the species of animals, birds, reptiles and insects from the
primeval flood which destroyed the universe. Hence man is also known as
manushya or Manav.
to Jain legends, Lord Mahavira, the last of the Jain Thirthankaras is
said to have attained final liberation or Nirvana at Pavapuri and the
first disciple of Mahavira, Ganadhar Gautam Swami also attained
complete knowledge on this very day. Jains celebrate this occasion by
lighting lamps at midnight and reading scriptures.
