Saint Namdev learned from the devotee Vithoba that God or Lord Shiva is present everywhere in this Universe, in all living and non-living things. With this learning He soon experienced God's presence everywhere and remained with God wherever He went.

One day, Lord Shiva appeared to Saint Namdev in a dream and said, "You are a good devotee of mine but you still have to learn something before you can be with me all the time. Visit the temple and meet another one of my devotees. His name is Vithoba. After that, tell me what you have learned from him." Then Lord Shiva disappeared. Namdev woke up in the morning and as per Lord Shiva's guidance, He set out to visit the temple.
When Namdev got to the temple, he inquired about the devotee Vithoba. While He was waiting, ‪ Namdev saw an old man, sitting with his feet on the statue of Lord Shiva. Namdev could not believe that a man could disrespect Lord Shiva like that. Just then the temple priest introduced Namdev to the old man, saying that the old man was Vithoba.
Namdev was quite confused! What could He learn from someone who was so disrespectful towards God! Just then Vithoba said, 'O Namdev, I am so old that it is difficult to even move my limbs. Please move my feet to a place where there is no God." Namdev began to move the old man's legs here and there, but wherever He put the old man's legs, Lord Shiva appeared !
Repentant, Namdev fell to the feet of the devotee Vithoba and begged for his forgiveness. ‪Thus, Saint Namdev learned from the devotee Vithoba that God or Lord Shiva is present everywhere in this Universe, in all living and non-living things. With this learning He soon experienced God's presence everywhere and remained with God wherever He went.
All Glories to The King of the Universe ~ Har Har Mahadev!!!!
