Bhagavatapurana 4.29.48

4.29.48

svaṃ lokaṃ na vidus te vai yatra devo janārdanaḥ /
āhur dhūmra-dhiyo vedaṃ sakarmakam atad-vidaḥ //

48. Those who have a smoky (confused) understanding and say that the Veda deals with Karma (sacrificial performances) do not grasp the real purport of the Veda: for they do not see the truth of Atman forming their own essential nature as intended by the Veda through which the Lord Janardana has to be sought and realised.
