Explanation:

Aranyakas are generally the concluding portions of the several Brahmanas, but on account of their distinct character, contents and language deserve to be reckoned as a distinct category of literature.
They are partly included in the Brahmanas themselves, but partly they are recognized as independent works. Aranyaka literature is rather small as compared to the Brahmanas.
The term Aranyaka is derived from the word 'Aranya' meaning 'forest'. The Aranyaka texts are so-called because 'they were works to be read in the forest' in contradistinction to the regular Brahmanas, which were to be read in the village.
Whereas the Brahmanas deal with the huge bulk of sacrificial paraphernalia which represents Karma-Kanda, the
Aranyakas and Upanishads, on the other hand, chiefly deal with the philosophical and theosophical speculations which represent Jnana-Kanda.
