b). The Four Vedas and Their Sub Divisions : 2.
The Brahmana portions guide people to perform sacrificial rites. They are prose explanations of the method of using the Mantras in the Yajna or the sacrifice. The Brahmana portion is suitable for the householders.
The Aranyakas are the forest books, the mystical sylvan texts which give philosophical interpretations of the rituals. The Aranyakas are intended for the Vanaprasthas or hermits who prepare themselves for taking Sannyasa.
The Upanishads are the most important portion of the Vedas. The Upanishads contain the essence or the knowledge portion of the Vedas. The philosophy of the Upanishads is sublime, profound, lofty and soul-stirring. The Upanishads speak of the identity of the individual soul and the Supreme Soul. They reveal the most subtle and deep spiritual truths. The Upanishads are useful for the Sannyasins.
The subject matter of the whole Veda is divided into Karma-Kanda, Upasana-Kanda and Jnana-Kanda. The Karma-Kanda or Ritualistic Section deals with various sacrifices and rituals. The Upasana-Kanda or Worship-Section deals with various kinds of worship or meditation. The Jnana-Kanda or Knowledge-Section deals with the highest knowledge of Nirguna Brahman. The Mantras and the Brahmanas constitute Karma-Kanda; the Aranyakas Upasana-Kanda; and the Upanishads Jnana-Kanda.
