Karmakāṇḍa and jñānakāṇḍa
The Vedas are traditionally divided into two broad portions. The karmakāṇḍa — mainly the Saṃhitās and Brāhmaṇas — gives hymns and instructions for rites. The jñānakāṇḍa — mainly the Upaniṣads — turns inward, asking about the Self and the ultimate reality, Brahman.
The two are not rivals. Many teachers describe ritual as preparation: it trains discipline, gratitude and focus, and so readies the mind for deeper understanding. The Bhagavad Gītā joins them by teaching that action done without selfish attachment itself becomes a path.
