“Without the oil, how can the lamp be lit? Let the reading of your prayer book be the oil, and let the Fear of God be the wick for the lamp of this body. Light this lamp with the understanding of Truth. Use this oil to light this lamp. Light it, and meet your Lord and Master.”
~Sri Guru Granth Sahib
A “diya” is traditionally made of clay. It represents the element of Agni or Fire in a ritual. The diya is filled with ghee or oil, which work as fuel for it. A wick made of cotton is inserted into the diya.
