WHY DO WE LIGHT A LAMP?

In almost every Indian home a lamp is lit daily before the altar of the Lord. In some houses it is lit at dawn, in some both at dawn and dusk, and in some it is maintained continuously - "akhanda deepa".
Light
symbolises knowledge. The Lord is the "Knowledge Principle"- "chaitanya".
Hence Light is worshipped as the Lord himself.
Knowledge
removes ignorance just as light removes darkness. Hence we light the lamp to bow
down to knowledge as the greatest of all forms of wealth.
The
oil or "ghee" in the lamp symbolises our "vaasnas"
or negative tendencies and the wick symbolises the ego. When lit by
spiritual knowledge, the "vaasnas" get slowly exhausted and ego
too finally perishes.
The
flame of a lamp always burns upwards. It teaches us to acquire such knowledge as
to take us towards higher ideals.
A
single lamp can help light many more just as a man of knowledge can share it
with many more. It does not diminish the brilliance of the light just as
knowledge isn't lessened by being shared.
"What else shall beautify a home
But the flame of a lovely lamp?
What else shall adorn the mind
But the light of wisdom deep?"
