A Religious Scholar, Pundit Gopal Das who was an Idol Worshiper, worship Shivalingam and wear Beads of Tulsi. Moreover he observed many ritualistic practices. He listened to Sacred Hymns of GURU SAHIB. When he listened to GURU SAHIB, he came to him and had Religious Discourse with him.

GURU SAHIB adviced him to understand various aspects of soul and controls evils and vices which have degraded his soul. To purify heart and Mind and understand the God inside him, as he could be attained through inside rather then stick to temporal things like Salisgram, Bathing, Wearing Beads etc. The whole religious discourse made Gopal Das sikh of the philosophy preached by GURU SAHIB and he left whole ritualistic practices.

When he heard about GURU SAHIB's philosophy is brilliant and no one could stand before it. He became angry and thought of having discussion with GURU SAHIB and beat him. With this mind he arrived to dwelling place of GURU SAHIB. He also brought with him some of his friends. When Pandit Chatur Dass saw GURU SAHIB the bad ideas in his mind were almost washed away. He forget himself. His inner soul was blessed. But still he asked GURU SAHIB that he has few question which he wanted to be answered by you. With your permission should i ask. GURU SAHIB asked that if you have any questions then theres a dog in this garden. Some times back he was A Knowledge able Pandit. But because of some reasons he became Dog.
