[3] The other parts of the Vedas are the Samhitas (benedictions, hymns), Brahmanas (commentary), and the Upanishads (spirituality and abstract philosophy).
[6] The Aitareya Aranyaka includes explanation of the Mahavrata ritual from ritualisitic to symbolic meta-ritualistic points of view.
[9] In the immense volume of ancient Indian Vedic literature, there is no absolute universally true distinction between Aranyakas and Brahmanas.
[11] The transition completes with the blossoming of ancient Indian philosophy from external sacrificial rituals to internalized philosophical treatise of Upanishads.
[12] "Aranyaka" (āraṇyaka) literally means "produced, born, relating to a forest" or rather, "belonging to the wilderness".
Originally, as per Oldenberg (1915),[15] it meant dangerous texts to be studied in the wilderness (Taitt.
A later, post-Vedic theory holds that these texts were meant to be studied in a forest, while the other holds that the name came from these being the manuals of allegorical interpretation of sacrifices, for those in Vanaprastha (retired, forest-dwelling) stage of their life, however the Vanaprastha Ashrama came into existence only well after that of the Sanyasin (Sprockhoff 1976), according to the historic age-based Ashrama system of human life.
It is mostly in helping the society in whatever manner possible, giving benefit of long experience and knowledge accumulated during the lifetime.
Linguistically and stylistically also, these works form a transition between the Brahmanas proper and the speculative literature that follows them and develops part of the ideas and lines of thought which are characteristic of them.
Many Aranyaka texts enumerate mantras, identifications, etymologies, discussions, myths and symbolic interpretations, but a few such as by sage Arunaketu include hymns with deeper philosophical insights.
[7] The Aranyakas discuss sacrifices, in the language and style of the Brahmanas, and thus are primarily concerned with the proper performance of ritual (orthopraxy).
It is in this portion of the Aranyaka that one finds specific statements about how one who follows the vedic injunctions and performs the sacrifices goes to become the God of Fire, or the Sun or Air and how one who transgresses the Vedic prescriptions is born into lower levels of being, namely, as birds and reptiles.
The first two chapters are part of the aṣṭau kāṭhakāni (the "8 Kathaka sections"),[19] which were not native to the tradition of the Taittiriya shakha.
They were adopted from the Kāṭhaka shakha, and mostly deal with varieties of the Agnicayana ritual[20] and with Vedic study.
Further, the sacred thread, the yajñopavīta, sāndhyā worship, that of the ancestors (pitṛ), the brahma-yajña, and the cleansing homa-sacrifice ('kūṣmāṇḍa-homa') are all treated in detail.
Chapter 4, provides the mantras used in the pravargya Shrauta ritual that is considered to be dangerous as it involves heating a specially prepared clay vessel full of milk until it is glowing red.
Chapter 6, records the ‘pitṛmedha’ mantras, recited during the rituals for the disposal of the dead body.
All divine personalities are inherent in the Purusha, just as Agni in speech, Vayu in Prana, the Sun in the eyes, the Moon in the mind, the directions in the ears and water in the potency.
Chapter 13 treats more philosophical matters and says one must first attitudinally discard one's bodily attachment and then carry on the ‘shravana’, manana and nidhidhyasana and practise all the disciplines of penance, faith, self-control etc.
Like the Taittiriya and Katha Aranyakas it exclusively deals with the Parvargya ritual, and is followed by the Brihad-Aranyaka Upanishad (Satapatha Br.
