http://spotlesswasche.com/blog/diwali-and-cleanliness/ Diwali is India’s premier festival – the Festival of Lights – celebrated with pomp and pageantry all over the land. It signifies the victory of good over evil, and wealth over poverty. Oil lamps light up the evenings and the nights; beautiful color patterns, called rangoli,decorate the entrance to every home and hearth; and friends and relatives gather together for a time of jollity and merrymaking.
