Those who are deriding the Godhood of Krishna are considered as demons and raksasas. There was only one raksasa at the time of Lord Ramacandra who did not care for the Lord and attempted to kidnap his wife so he took away maya-laksmiji from Narayana. The result was that he became ruined with his whole family and kingdom. In this age of kali there are a number of Ravanas deriding the Godhood of Lord Krishna and Lord Ramacandra, and they will meet with the same result as it was done in the case of Ravana. So it is a dangerous position of the whole world that they have become all godless or atheists in different degree or manner. It is the duty of saintly persons to save these rascals from ruination. So, I wish that a devotee of Lord Krishna like you may conjointly work in propagating Krishna Consciousness to save the fallen souls from going down to the darkest region of hell.
