Dear Sikh80ji,
I do believe that guru nanak never claimed to be an incarnate of vishnu but i don't agree with the view that he was not in favour of teachings of vedas.
Nanak do accept the teachings of vedas but he said that in Kalyuga the teachings of Vedas has been replaced by the words of Guru (Gurbani).
The Vedas also speak of the same lord and i think no where its written that nanak rejected the teachings of Vedas.
The corruption that has occured in hinduism is not because of vedas but because of false spiritual practices being followed by hindu people.
9th Guru says :
बेद पुरान पड़े को इह गुन सिमरे हरि को नामा ॥१॥ रहाउ ॥
This is the blessing of studying the Vedas and the Puraanas, that you may meditate on the Name of the Lord. ||1||Pause||
Nanak Says :
घोखे सासत्र बेद सभ आन न कथतउ कोइ ॥
I have searched all the Shaastras and the Vedas, and they say nothing except this:
आदि जुगादी हुणि होवत नानक एकै सोइ ॥१॥
“In the beginning, throughout the ages, now and forevermore, O Nanak, the One Lord alone exists”. ||1||
बेद पुरान सिम्रिति बूझै मूल ॥
He understands the fundamental essence of the Vedas, the Puraanas and the Simritees.
Nanak says :
वेदा महि नामु उतमु सो सुणहि नाही फिरहि जिउ बेतालिआ ॥
In the Vedas, the ultimate objective is the Naam, the Name of the Lord; but they do not hear this, and they wander around like demons.
You will find the following verse also in granth sahib which clearly states that :
बेद कतेब कहहु मत झूठे झूठा जो न बिचारै ॥
Do not say that the Vedas, the Bible and the Koran are false. Those who do not contemplate them are false.
Lord krishna is held in high respect in Granth sahib following verses show that :
