Also Christmas lights; they are even called Christmas lights because in Christmas season you like to light up the whole place. In Deepavali, lighting a lot of lamps creates an atmosphere of celebration.
That is what ‘deep’ pooja is.
Our life is like light, so lighting the light of wisdom within each one of us and lighting the light of love.
You will see here in India, the lamps have got five wicks and the five wicks symbolize the five senses. Let there be awareness and light in the five senses, that is the wish.
Our body is like a lamp and it has five senses and they should all be lit.
