Shivananda Maharaj describes Indian Mythology as follows:

Vedas
The Vedas are considered the earliest literary record of Indo-Aryan civilization, and the most sacred books of India. They are the original scriptures of Hindu teachings, and contain spiritual knowledge encompassing all aspects of our life. Vedic literature with its philosophical maxims has stood the test of time and is the highest religious authority for all sections of Hindus in particular and for mankind in general.

"Veda" means wisdom, knowledge or vision, and it manifests the language of the gods in human speech. The laws of the Vedas regulate the social, legal, domestic and religious customs of the Hindus to the present day. All the obligatory duties of the Hindus at birth, marriage, death etc. owe their allegiance to the Vedic ritual. They draw forth the thought of successive generation of thinkers, and so contain within it the different strata of thought.

Origin of the Vedas
The Vedas are probably the earliest documents of the human mind and is indeed difficult to say when the
earliest portions of the Vedas came into existence. As the ancient Hindus seldom kept any historical record of their religious, literary and political realization, it is difficult to determine the period of the Vedas with precision. Historians provide us many guesses but none of them is free from ambiguity.

Who wrote the Vedas?
It is believed that humans did not compose the revered compositions of the Vedas, which were handed down through generations by the word of mouth from time immemorial. The general assumption is that the Vedic hymns were either taught by God to the sages or that they were revealed themselves to the sages who were the seers or "mantradrasta" of the hymns. The Vedas were mainly compiled by Vyasa Krishna Dwaipayana around the time of Lord Krishna (c. 1500 BC).

Classification of the Vedas
The Vedas are four: The Rig Veda, the Sama Veda, the Yajur Veda and the Atharva Veda, the Rig Veda being the main. The four Vedas are collectively known as "Chathurveda" of which the first three Vedas viz., Rig Veda, Sama Veda and Yajur Veda agree in form, language and content.

Structure of the Vedas
Each Veda consists of four parts - the Samhitas (hymns), the Brahmanas (rituals), the Aranyakas (theologies) and the Upanishads (philosophies). The collection of mantras or hymns is called the Samhita. The Brahmanas are ritualistic texts and include precepts and religious duties. Each Veda has several Brahmanas attached to it. The Upanishads form the concluding portions of the Veda and therefore called the "Vedanta" or the end of the Veda and contains the essence of Vedic teachings. The Upanishads and the Aranyakas are the concluding portions of the Brahmanas, which discuss philosophical problems. The Aryanyakas (forest texts) intend to serve as objects of meditation for ascetics who live in forests and deal with mysticism and symbolism.

The Mother of All Scriptures
Although the Vedas are seldom read or understood today, even by the devout, they no doubt form the bedrock of the universal religion or "Sanatana Dharma" that all Hindus follow. The Vedas have guided our religious direction for ages and will continue to do so for generations to come. And they will forever remain the most comprehensive and universal of all ancient scriptures.


Upanishads
The Upanishads form the core of Indian philosophy. They are an amazing collection of writings from original oral transmissions, which have been aptly described by Shri Aurobindo as "the supreme work of the Indian mind". It is here that we find all the fundamental teachings that are central to Hinduism - the concepts of "karma" (action), "samsara" (reincarnation), "moksha" (nirvana), the "atman" (soul), and the "Brahman" (Absolute Almighty). They also set forth the prime Vedic doctrines of self-realization, yoga and meditation. The Upanishads are summits of thought on mankind and the universe, designed to push human ideas to their very limit and beyond. They give us both spiritual vision and philosophical argument, and it is by a strictly personal effort that one can reach the truth.
Meaning of "Upanishad"
The term "Upanishad" literally means, "Sitting down near" or "Sitting close to", and implies listening closely to the mystic doctrines of a guru or a spiritual teacher, who has cognized the fundamental truths of the universe. It points to a period in time when groups of pupils sat near the teacher and learnt from him the secret teachings in the quietude of forest "ashrams" or hermitages. In another sense of the term, "Upanishad" means "brahma-knowledge" by which ignorance is annihilated. Some other possible meanings of the compound word "Upanishad" is "placing side by side" (equivalence or correlation), a "near approach" (to the Absolute Being), "secret wisdom" or even "sitting near the enlightened".

Time of Composition
Historians and Indologists have put the date of composition of the Upanishads from around 800-400 B.C., though many of the verse versions may have been written much later. In fact, they were written over a very long period of time and do not represent a coherent body of information or one particular system of belief. However, there is a commonality of thought and approach.
