Clay diyas are symbolically lit during prayers rituals and ceremonies; they are permanent fixtures in homes and temples. The warm bright glow emitted from a diya is considered auspicious - it represents enlightenment prosperity knowledge and wisdom. Diyas represent the triumph of light over dark good over evil with the most notable example of this being on the day of Diwali. Diwali is celebrated every year to celebrate the triumph of good over evil as told in the Hindu epic the Ramayana. Diwali marks the day Lord Rama Goddess Sita and Lakshmana returned home to Ayodhya after 14 years in exile away from their home fighting and eradicating evil. To welcome Lord Rama Goddess Sita and Lakshmana home citizens of Ayodhya lit up the streets with diyas.
