"O Arjuna! Men of less wisdom presume inquisitive anagoges of the Vedas and presume Heaven as the sovereign destination and argue that there is nothing beyond the heaven, and pleasures, they only gratify the statements of Vedas according to pleasure of their sense. Preoccupied by desires, they perform numerous orientations rituals producing of good birth, wealth and power for the attainment of pleasure and prosperity."
Purport
In these shlokas Bhagvan Shri Krishna explained Arjuna, that those people who assume svarg(Heaven) as supreme are wrong. Such people actually takes convenient meaning under the spell of their own desires to achieve material pleasures in heaven.
