Out of six orthodox Hindu Philosophical schools, Vedanta and Mimamsa directly philosophize the Gyanakanda and Karmakanda of the Vedas.
The other four schools (Nyaya, Vaisheshika, Samkhya and Yoga) have their own philosophical ideas. However, they accept the authority of the Vedas (that is why these are in the fold of Hinduism).
There must be some verses in their respective Sutras that declare it explicitly. I want to know these verses. Please quote directly from the Sutras or their commentaries but not from other secondary sources.
