Once Lord Vishnu got bored sitting on Sheshnag, and he thought of roaming on the earth, many years had passed since he came to the earth, and he started preparing for his journey, seeing Swami getting ready Lakshmi Maa asked!! Vishnu ji said, O Lakshmi, I am going to roam the earth, then Lakshmi Ma said after thinking something! Oh God, can I also go with you???? Lord Vishnu thought for a moment and then said on one condition, you can walk with me, you reach the earth and do not look towards the north direction at all.
