If that was the case and we shouldnt shy away from any god of house regardless of whether mandir or mosque.....would guru have gone through so much for us and tell us in detail not to do idol worship? If waheguru wanted us to do this what was the point of sending Guru Nanak Dev Ji to preach the true path...
Hindu gods - yes they were on earth, waheguru sent them...they come and went....it was all a creation of and a drama by the almighty
