The name “Diwali” is a contraction of “Deepavali” (Sanskrit: दीपावली Dīpāvalī), which translates into “row of lamps”. Diwali involves the lighting of small clay lamps (diyas or dīpas) in Sanskrit: दीप) filled with oil to signify the triumph of good over evil.

I first got to know about this festival on my first year in Bahrain, year 1999 where people who celebrate this festival,particularly the Hindus would go for shopping for new clothes and distribute sweets to friends and families. It’s like Christmas for them. I also remember wearing a set of saree at work, as required by our F&B Director. Every year, the Company where I worked for had this big event prepared for non-members of the Resort. It is usually an open day event at the Resort.
This is one of the most awaited festivals of Hindus that I know of.
