The Story of Namdev ji and a dog

Once, Muktabai asked Gora Kumbhar to test all saints present in her assembly. Gora Kumhar slapped each one on the heads to test as is done by potters. He also slapped on the head of saint Namdev ji. Namdev ji felt insulted; however, he did not say anything. He thought out of pride whether he could be tested like earthenware. The expressions of other bhaktas (devotees) were unchanged. Gora Kumhar conveyed his decision that heads (earthenware) of all except Namdev ji are strong.
 
Hearing the judgement of Gora Kumhar, Namdev ji reacted to him that rather his head is weak and he needs education. Namdev ji shared the entire episode to Vitdalnath ji. Vitdalnath ji said, if Muktabai and Gora Kumhar said this, then his head must be weak. Vitdalnath ji further said to him that he had not experienced the almighty Brahman as he did not take guidance from sadguru. He should go to his Bhakta Visoba Khecher to attain spiritual wisdom.
 
Namdev ji searched out Visoba Khecher in a Shiva temple. Namdev ji saw that Visoba was sleeping there by putting his legs on Shiva linga. Visoba knew that Namdev ji would be arriving so as to teach him a lesson, Visoba did this. When Namdev ji saw this, he thought, the person who is insulting the God, how can he give spiritual teachings. Namdev ji asked visoba to remove his legs from Shiva linga. Visoba asked him to place his legs in the direction where Shiva does not exist. Namdev ji tried to shift his legs in various directions but wherever he shifted the legs, Shiva linga appeared there. Namdev ji was highly surprised. Visoba told him that he is in fact weak. He is not able to have vision of almighty everywhere. In this universe, almighty is present everywhere in minute form. Hence, he should see almighty in all non-living & living beings.
 
Namdev ji, thereafter started having vision of almighty everywhere. On the way back, he sat under a tree to take his meal. Meanwhile, one dog escaped with his roti (bread). Today, Namdev ji saw almighty in the dog. Roti was dry. Hence, Namdev ji ran after him with butter saying stop, roti is dry. Let me apply butter on the roti.
 
Spiritual Significance:

1. If one believes that almighty is everywhere, then he would not find a place or time to do sin. 
2. Sins committed by body can be seen by people but sins done by mind can be seen by the almighty. Sins done by mind are worse.
3. Offering flowers, applying sandal wood paste etc. is not enough devotion, but to see almighty in everybody and everywhere is real bhakti (devotion).
