Guru Granth Views on Vedas

Gurbani is not against Vedas or any Religious Granths, but it is against mere reading those. Gurbani supports vichar, in Gurbani many times it come:

Ved Smiritis tell about God

ਬੇਦ ਸਿੰਮ੝ਰਿਤਿ ਕਥੈ ਸਾਸਤ ਭਗਤ ਕਰਹਿ ਬੀਚਾਰ੝ ॥ The Vedas, the Simritees, the Shaastras and the Lord's devotees contemplate Him;

Only Fools can't understand Vedas

ਬੇਦ ਬਖਿਆਨ ਕਰਤ ਸਾਧੂ ਜਨ ਭਾਗਹੀਨ ਸਮਝਤ ਨਹੀ ਖਲ੝ ॥
The Holy Saints preach the teachings of the Vedas, but the unfortunate fools do not understand them.

Against mere Reading

ਬੇਦ ਪੜਹਿ ਸੰਪੂਰਨਾ ਤਤ੝ ਸਾਰ ਨ ਪੇਖੰ ॥ Those who read the Vedas in their entirety, still do not see the sublime essence of reality.

ਪੜਹਿ means Read

ਬੇਦ ਕਤੇਬ ਸਿਮ੝ਰਿਤਿ ਸਭਿ ਸਾਸਤ ਇਨ੝ਹ੝ਹ ਪੜਿਆ ਮ੝ਕਤਿ ਨ ਹੋਈ ॥ One may mere read all the books of the Vedas, the Bible, the Simritees and the Shaastras, but they will not bring liberation mere reading.

ਬੇਦ ਪੜੇ ਪੜਿ ਬ੝ਰਹਮੇ ਹਾਰੇ ਇਕ੝ ਤਿਲ੝ ਨਹੀ ਕੀਮਤਿ ਪਾਈ ॥ Reading and reciting the Vedas, Brahma grew weary, but he did not find even a tiny bit of God's worth.

In Dasam Granth, these Simrit Shashtars are cleared.
