Diwali is celebrated as the festival of lights to symbolize the victory of light over darkness, good over evil, and knowledge over ignorance, and different Indian religions link it to their own sacred stories and events.

Quick Scoop

What is Diwali?

  • Diwali (or Deepavali) literally means “row of lights” in Sanskrit.
  • People light rows of clay lamps and decorate homes to represent inner light driving away spiritual darkness.
  • It is one of the biggest and most widely celebrated festivals in India and among the Indian diaspora worldwide.

Main Reasons Diwali is Celebrated

1. Symbolic meaning

  • Diwali symbolizes light over darkness, good over evil, and knowledge over ignorance.
  • Lamps, candles, and fireworks express hope, clarity, and the idea that positive forces ultimately win.

2. Hindu traditions (multiple stories)

Different regions emphasize different stories for why Diwali is celebrated:

  • Return of Lord Rama to Ayodhya
    • In many parts of North India, Diwali marks Rama, Sita, and Lakshmana returning to Ayodhya after 14 years of exile and the defeat of the demon king Ravana.
* People lit lamps to welcome them home, which is why houses are still illuminated today.
  • Krishna and Narakasura
    • In parts of South India, Diwali is linked to Krishna’s defeat of the demon Narakasura, ending his reign of terror.
* This story emphasizes destroying negativity and “hellish” suffering so a new light can shine in life.
  • Lakshmi, goddess of wealth
    • Diwali is commonly celebrated in honour of Lakshmi, the goddess of wealth and prosperity.
* People clean and decorate their homes, perform Lakshmi puja, and open doors and windows to “invite” prosperity and good fortune.

3. Jain, Sikh, and Buddhist perspectives

  • In Jainism, Diwali marks the nirvana (spiritual liberation) of Lord Mahavira, the last Tirthankara, in 527 BCE.
  • In Sikhism, it commemorates the day the sixth Guru, Guru Hargobind Ji, was released from imprisonment, often called “Bandi Chhor Divas.”
  • Some Buddhists in India also observe Diwali, integrating it into local traditions.

How people celebrate (and why that matters)

People celebrate Diwali in ways that reflect its meaning:

  • Lighting diyas (lamps) and candles to represent inner light and hope.
  • Cleaning and redecorating homes, symbolizing removing old negativity and inviting fresh beginnings.
  • Performing prayers (puja), especially to Lakshmi and sometimes to Ganesha, for prosperity and wisdom.
  • Sharing sweets, gifts, and visiting friends and family to strengthen community bonds.
  • Fireworks and festivities to express joy at the triumph of good over evil.

Deeper spiritual angle

  • Some modern spiritual teachers describe Diwali as a festival of “clarity”: lighting lamps is about clearing inner confusion and inertia so your own intelligence and goodness shine.
  • It’s also seen as a time to let go of anger, jealousy, fear, and other emotions that create a personal “hell,” and to start a new, brighter phase of life.

In many online forum discussions, people say Diwali is not just a religious event but a cultural anchor that reminds them once a year to “reset,” reconnect with loved ones, and consciously choose light over darkness in everyday decisions.

TL;DR

Diwali is celebrated because it brings together several powerful ideas at once: heroic victories from Hindu epics, key milestones in Jain and Sikh history, devotion to prosperity and well-being, and a universal message that light, goodness, and wisdom ultimately win over darkness and evil.
