“In a temple of Lord Visnu, there lived a mouse that daily ate the ghee from the extinguished ghee lamps, which had been offered to the Lord. One day when the mouse felt hungry, she tried to eat the ghee from a lamp that was not yet extinguished. While nibbling at the lamp, the cotton wick got stuck in her teeth. Since the ghee wick was still ablaze, the mouse, feeling the heat, started jumping up and down on the altar in front of the Deity; soon afterwards she died from the fire.
The all-merciful Lord Sri Visnu seeing the mouse jumping before Him with a lamp, assumed that she was offering Him aratik. Out of gratitude, He rewarded her with and exalted human birth in her next life from which she made further progress and then went back to Godhead.”
So, who will neglect the great opportunity to make progress in spiritual life, when even an insignificant mouse became the recipient of the Lord's mercy by inadvertently offering a flaming ghee wick to the Lord?
During the month of Kartik, observed from October 5th to the 3rd of November, anyone who invests a few moments of their valuable time to worship Lord Krishna by simply offering a ghee lamp, becomes the recipient of tremendous blessing. Good investment, no?
