According to Dr. K. S. Narayanacharya, these are four different modes of expressing the same truths, each as a cross check against others so that misrepresentations are avoided, a method used and valid even today.<ref name=":2222">Insights Into the Taittiriya Upanishad, Dr. K.

Chronology and dating of Upanishads is not attempted in this article.

The Upanishads speak about the identity of the Supreme Being, the Brahman, the individual Atman, their mutual relationship, the Universe (jagat) and man’s place in it. In short they deal with Jiva, Jagat and Jagadishwara and ultimately the path to ''mokṣa'' or ''mukti.''<ref>http://www.esamskriti.com/e/Spirituality/Upanishads-Commentary/Vedas-And-Upanishads~-A-Structural-Profile-3.aspx</ref> Chronology and dating of Upanishads is not attempted in this article.

==उपनिषद्विषयाः ॥ Upanishad Vishaya==

 

Some terms which are well explained in the Upanishads include, Prkriti (प्रकृतिः), Purusha (पुरुषः), Paramatma (परमात्मा), Ishvara (ईश्वरः), Jivatma (जीवात्मा), Maya (माया), Brahman (ब्रह्मन्), Avidya (अविद्या), Indriyas (इन्द्रियानि),  etc. From the root cause Prkriti the world came into being. Paramatma is Nitya, Puratana, Shasvata (Eternal) devoid of the cycles of birth and death. The Sharira or body is subjected to death and birth but Atma residing in it continues to exist. Just like butter is evenly distributed in milk so also Paramatma is all-pervading in the world. Just like the sparks arise out of fire so also the beings take shape from the Paramatma. Such aspects which are explained in Upanishads have widely developed in the Darshana shastras.

The Upanishads include sections on certain siddhantas that have been the very foundation of [[Sanatana Dharma (सनातनधर्मः)|Sanatana Dharma]]. For example, the Chandogya Upanishad includes one of the earliest known declaration of Ahimsa (non-violence) as an ethical precept. Discussion of other ethical premises such as Damah (temperance, self-restraint), Satya (truthfulness), Dāna (charity), Ārjava (non-hypocrisy), Daya (compassion) and others are found in the oldest Upanishads and many later Upanishads. Similarly, the Karma doctrine is presented in the Brihadaranyaka Upanishad, which is the oldest Upanishad.

=== एकं सत् The One Existence ===

Worship of the nature and devatas such as the ''Agni'', ''Aditya'', ''Indra'', ''Rudra'', ''Visnu'', ''Brahma'' and others becomes internalized in the Upanishads to the meditation on the supreme, immortal and formless Brahman-Atman. The many names of devatas with forms and weapons gradually merged into defining a One Existence, a supreme being called now as Paramatma, Brahman etc. <blockquote>एकं सद्विप्रा बहुधा वदन्ति (Rig. Veda. 1.164.46)</blockquote>Devatas who held positions in the outer worlds are now declared to be everywhere, even as the innermost being of each human being and within every other living creature.  <blockquote>एकमेवाद्वितीयं ब्रह्म (Chand. Upan. 6.2.1)</blockquote>What was One reality or ''ekam'' satofthe Vedas now becomes the ekam eva advitiyam brahma'' or "the one and'' ''only and sans a second''" in the Upanishads. Discussion of Brahman-Atman and Self-realization develops in the Upanishads as the means to moksha (liberation, freedom in this life or after-life). Worship which was primarily of the nature and natural elements (like fire, clouds and rains, air) with deities having a form and qualities called Saguna Brahman transformed to worship of "Tat" (That) without attributes, qualities, beyond name and form called as Nirguna Brahman. The qualities or the nature of Nirguna Brahma includes Infinite, Absolute, Eternal, Changeless, the All

Formless and nameless be the description of Nirguna Brahma, however, his nature is Infiniteness, Absoluteness, Eternity, Changelessness finally it constitutes All That is (अस्तीति). (Shev. Upan. 4.18) That which is beyond number and name is denoted by one sound called Pranava. Tattriyopanishad, Shikshavalli contains the stuti of Pranava in the eighth anuvaka as follows

 

Brahman and Atman are two concepts that are unique to Indian knowledge systems which are highly developed in the Upanishads. The word Brahman is used to represent the all pervading, ultimate reality without a second. The  concept that brahman and jagat (world) are completely distinct from each other is dismissed and the tattva is explained. For example, Chandogya Upanishad describes the unity of Jiva and Brahman, in the form of conversation between [[Uddalaka and Shvetaketu (उद्दालकः श्वेतकेतुः च।)|Uddalaka and Shvetaketu]].
