The Vedas have been divided into four styles of texts – the Samhitas, the Aranyakas, the Brahmanas and the Upanishads. 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 Samhitas and the Brahmanas constitute Karma-Kanda; the Aranyakas constitute Upasana-Kanda; and the Upanishads constitute Jnana-Kanda<ref>Swami Sivananda, All About Hinduism, Page 30-31</ref><ref name=":02">Sri Sri Sri Chandrasekharendra Saraswathi Swamiji, (2000) ''[http://www.kamakoti.org/hindudharma/part19/chap6.htm Hindu Dharma (Collection of Swamiji's Speeches between 1907 to 1994)]''Mumbai : Bharatiya Vidya Bhavan</ref>The Upanishads along with the Bhagavadgita and Brahmasutras constitute the Prasthana Trayi (प्रस्थानत्रयी) and both the Gita and Brahmasutras are based again on the Upanishads.

*विशरण (नाशनम्) to destroy : They destroy the seeds of Avidya causing samsara in a Mumukshu (a sadhaka who wants to attain Moksha), hence this Vidya is called Upanishads<blockquote>अविद्यादेः संसारबीजस्य विशरणाद् विनाशनादित्यनेन अर्थयोगेन विद्या उपनिषदुच्यते । avidyādeḥ saṁsārabījasya viśaraṇād vināśanādityanena arthayogena vidyā upaniṣaducyate ।</blockquote>

*गति (प्रपणम् वा विद्यर्थकम्) to obtain or to know : That vidya which leads to  or make the sadhaka obtain Brahma, is called Upanishad.<blockquote>परं ब्रह्म वा गमयतोति ब्रह्म गमयितृत्वेन योगाद् विद्योपनिषद् । paraṁ brahma vā gamayatoti brahma gamayitr̥tvena yogād vidyopaniṣad ।</blockquote>

Shankaracharya's commentaries of the Kaṭha and Brihadaranyaka Upanishad also support this explanation.

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, Jnana and Jagadishwara and ultimately the path to Brahman called as ''mokṣa'' or ''mukti.''<ref>http://www.esamskriti.com/e/Spirituality/Upanishads-Commentary/Vedas-And-Upanishads~-A-Structural-Profile-3.aspx</ref>

==== Brahman and Atman ====

==== Brahman and Atman ====

Brahman and Atman are two concepts that are unique to Indian knowledge systems which are highly developed in the Upanishads. 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.<ref name=":1" /><ref name=":4" />

One which is described as without a second, is Infinite, Absolute, eternal is called as तत् । THAT, without attributes, gunas, beyond name and form, and cannot be explained by any similies or worldly descriptions is the Nirguna Brahman.

One which is described as without a second, is Infinite, Absolute, eternal is called as तत् । THAT, without attributes, gunas, beyond name and form, and cannot be explained by any similies or worldly descriptions is the Nirguna Brahman.  

A very important concept of Brahman being gross and subtle is raised by Satyakama and so explained in the Prashnopanishad. <blockquote>एतद्वै सत्यकाम परं चापरं च ब्रह्म यदोङ्कारः । (Pras. Upan. 5.2)<ref>Prashnopanishad ([https://sa.wikisource.org/wiki/%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%B6%E0%A5%8D%E0%A4%A8%E0%A5%8B%E0%A4%AA%E0%A4%A8%E0%A4%BF%E0%A4%B7%E0%A4%A4%E0%A5%8D/%E0%A4%AA%E0%A4%9E%E0%A5%8D%E0%A4%9A%E0%A4%AE%E0%A4%83_%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%B6%E0%A5%8D%E0%A4%A8%E0%A4%83 Prashna 5])</ref></blockquote>Meaning : Verily, O Satyakama, this Omkara is the Supreme and the lower Brahman.<ref name=":022" />

Chandogya Upanishad clearly expounds the Nirguna Brahmatattva through the Mahavakya<blockquote>एकमेवाद्वितीयम्। One only, without a second. (Chand. Upan. 6.2.1)<ref>Chandogya Upanishad ([https://sa.wikisource.org/wiki/%E0%A4%9B%E0%A4%BE%E0%A4%A8%E0%A5%8D%E0%A4%A6%E0%A5%8B%E0%A4%97%E0%A5%8D%E0%A4%AF%E0%A5%8B%E0%A4%AA%E0%A4%A8%E0%A4%BF%E0%A4%B7%E0%A4%A6%E0%A5%8D/%E0%A4%85%E0%A4%A7%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%AF%E0%A4%83_%E0%A5%AC Adhyaya 6])</ref></blockquote>Shevatasvatara Upanishad  <blockquote>यदाऽतमस्तन्न दिवा न रात्रिर्न सन्नचासच्छिव एव केवलः ।... ॥ १८ ॥ (Shvet. Upan. 4.18)<ref>Shvetashvatara Upanishad ([https://sa.wikisource.org/wiki/%E0%A4%B6%E0%A5%8D%E0%A4%B5%E0%A5%87%E0%A4%A4%E0%A4%BE%E0%A4%B6%E0%A5%8D%E0%A4%B5%E0%A4%A4%E0%A4%B0%E0%A5%8B%E0%A4%AA%E0%A4%A8%E0%A4%BF%E0%A4%B7%E0%A4%A4%E0%A5%8D/%E0%A4%9A%E0%A4%A4%E0%A5%81%E0%A4%B0%E0%A5%8D%E0%A4%A5%E0%A4%83_%E0%A4%85%E0%A4%A7%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%AF%E0%A4%83 Adhyaya 4])</ref></blockquote>When there was mere tamas, and neither day nor the night, neither the universe (having a form) or without a form, there existed that pure auspicious principle alone signifying the One Principle.<blockquote>द्वे अक्षरे ब्रह्मपरे त्वनन्ते विद्याविद्ये निहिते यत्र गूढे । क्षरं त्वविद्यां ह्यमृतं तु विद्या विद्याविद्ये ईशते यस्तु सोऽन्यः ॥ १ ॥</blockquote>A very important concept of Brahman being gross and subtle is raised by Satyakama and thus explained in the Prashnopanishad. <blockquote>एतद्वै सत्यकाम परं चापरं च ब्रह्म यदोङ्कारः । (Pras. Upan. 5.2)<ref>Prashnopanishad ([https://sa.wikisource.org/wiki/%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%B6%E0%A5%8D%E0%A4%A8%E0%A5%8B%E0%A4%AA%E0%A4%A8%E0%A4%BF%E0%A4%B7%E0%A4%A4%E0%A5%8D/%E0%A4%AA%E0%A4%9E%E0%A5%8D%E0%A4%9A%E0%A4%AE%E0%A4%83_%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%B6%E0%A5%8D%E0%A4%A8%E0%A4%83 Prashna 5])</ref></blockquote>Meaning : Verily, O Satyakama, this Omkara is the Supreme and the lower Brahman.<ref name=":022" />

Brhdaranyaka Upanishad also says the following<blockquote>द्वे वाव ब्रह्मणो रूपे मूर्तं चैवामूर्तं च मर्त्यं चामृतं च स्थितं च यच्च सच्च त्यच्च ॥ १ ॥ (Brhd. Upan. 2.3.1)<ref>Brhdaranyaka Upanishad ([https://sa.wikisource.org/wiki/%E0%A4%AC%E0%A5%83%E0%A4%B9%E0%A4%A6%E0%A4%BE%E0%A4%B0%E0%A4%A3%E0%A5%8D%E0%A4%AF%E0%A4%95_%E0%A4%89%E0%A4%AA%E0%A4%A8%E0%A4%BF%E0%A4%B7%E0%A4%A6%E0%A5%8D_2p Adhyaya 2])</ref></blockquote>Meaning : There are two states of Brahman, मूर्तं । gross (with form) and अमूर्तं । subtle (formless), mortal (मर्त्यं) and immortal (अमृतं), finite and infinite, existent and beyond (existence).<ref>Swami Madhavananda, (1950).
