In reading through chapter 7 of this online English version of Satyarth Prakash we find that Dayanad Saraswati was very politically incorrect and had very strong opinions. He basically distinguishes between the authentic religion of the Vedas and the corrupted teachings found in everything else including the Bhagavad Gita. He asserts that confusion developed over time as Indians were trying to incorporate teachings of the Vedas with primitive polytheistic beliefs and a misunderstanding of some of the Vedas, which he claimed were absolutely monotheistic. He also expresses criticism for the pro-westernizing movements such as Brahmo Samaj and for the origins of Sikhism under Guru Nanak whom he criticized for how Guru Nanak characterized the Vedas. It is an extremely interesting perspective.
