O Partha, those of small intelligence misinterpret the Vedas and claim that there is no divine principle in creation. Thus they glorify those statements that are pleasing to the senses.
Because their hearts are filled with selfish desires and their goal is the higher planets, they prescribe many rituals that award higher birth, wealth and power and lead to enjoyment and opulence.
By such ideas these persons, contemplating sense gratification and mundane pleasures, do not attain the resolve to fix their minds on the Supreme.
The Vedas deal with subjects in the three modes of material nature. O Arjuna, become free from duality, situated in a state of pure spiritual consciousness, free from the pursuits for gain and preservation and thus you will transcend these three modes.

Your right is to perform your work, but never to the results. Never be motivated by the results of your actions, nor should you be attached to not performing your prescribed duties.
