Bhagavad Gita Chapter 2 Sloka 43 (2.43)

ಕಾಮಾತ್ಮಾನಃ ಸ್ವರ್ಗಪರಾ ಜನ್ಮಕರ್ಮಫಲಪ್ರದಾಮ್ ।
ಕ್ರಿಯಾವಿಶೇಷಬಹುಲಾಂ ಭೋಗೈಶ್ವರ್ಯಗತಿಂ ಪ್ರತಿ ॥೪೩॥
kāmātmānaḥ svargaparā janmakarmaphalapradām |
kriyāviśeṣabahulāṃ bhogaiśvaryagatiṃ prati ||43||
Gist of the sloka:
These people stop at the thoughts that the Vedas is meant to be means to perform various actions [fire sacrifices homas/yagnas] and are happy at the external meaning of the poetic words.
Explanation:
Purva mimansakaru is one such category of people, whose sole objective is to perform the various yagnas, obtain heavenly positions and once the karmas expire come back and redo the exercise again and again. They do not try to understand the inner intent or deeper meaning of the Vedas.
The Vedas hide such secrets of self-realization, which when understood elevates the soul to mukthi.
