After being here on SPN and going through the opinions of various members on The God and the creation,Karma, Liberation and allied concepts of sikhism It is not wrong to say that sikhism is just an ultra modern form of Hinduism or Vedantism.
I do not have in depth knowledge of both the religions but to me it appears that both the religions are same there is superficial difference created for purpose.
Excluding the outer appearance of the sikhs they intrinsically are just the Hindus.There is no essential difference between a sikh and a Hindu. If any one has a different opinion one may post and I shall reply mostly from Geeta i.e. stated to be the conceptually summarized format of Vedas and Upnishdas and some other booklets published by the Leading publishers on Hinduism. I shall also have the liberty of quoting the opinion of the members of this forum from the various posts.
I am a sikh and have been trying to understand this as a different faith but fail to find any material difference between the two and do feel and understand as to why Indian Government has not classified it as a separate religion.
You will have to bear with my presentation and my English.
