By P.R.Ramachander

Sometimes transliterated as: Upanisad, UpaniSad, Upanishad


The term "Upaniṣad" literally means the inner or mystic teaching. It is derived from upa,[1] ni[2] and s(h)ad,[3] i.e., sitting down near, which refers to groups of pupils sitting near their teacher to learn from him the secret doctrine. In the serenity of forest hermitages, the Upaniṣad thinkers pondered on the problems of deepest concerns and communicated their knowledge to the capable pupils that sat near them.

Samkara derives the word Upaniṣad as a substitute from the root sad, 'to loosen,' 'to reach' or 'to destroy' with Upa and ni as prefixes and kvip as termination. If this determination is accepted, Upaniṣad means brahma-knowledge by which ignorance is loosened or destroyed. The Upaniṣads are found in the concluding sections of the Vedas and are classified as Vedanta or the end of the Vedas.

There are five Vedas and each of these five books has several Sākas.[4] Each Sāka has a Karma Khanda dealing with the actions to be performed and is made up of Mantras and Brahmanās. The latter deals with Upāsana or meditation and has Aranyakas inside them for the benefit of those who have resorted to the quiet habitat of the forest to pursue their spiritual quest.

The Upaniṣads are found mostly in the Aranyaka section of the Vedas. The five Vedas have 1180 Sākas and thus there should be 1180 Upaniṣads. Of these, what exists today is a collection of 108 Upaniṣads. The list of these 108 Upanishads is given in the Mukthikopaniṣad.

Out of the 108 Upaniṣads, only 10 have been commented upon by several Ācharyas like Ādi Śankarācharya. These are Ishavasya, Kena, Katha, Aithreya, Brihadaranyaka, Prashna, Mandukya, Taittireeya, Chandogya and Mundaka. These have also been popularized by many savants like Swami Vivekananda, Swami Chinmayānanda etc. They all deal with highest category of philosophy and metaphysics. Because of this, there is a general impression that all Upaniṣads are texts of Hindu Philosophy. This is not true. There are Upaniṣads which even tell you how to wear the sacred ash, how to worship a particular God and so on. But the majority of them deal with methods of Yoga and Renunciation.[5]

"From every sentence of the Upaniṣads deep, original and sublime thoughts arise, and the whole is pervaded by a high and holy earnest spirit...In the whole world there is no study so beneficial and so elevating as that of the Upanishads. They are destined sooner or later to become the faith of the people." - Dr. Arthur Schopenhauer

Major Upaniṣads

The ten major Upaniṣads which contain great philosophical discussions and knowledge are:

Ishāvasya Upaniṣad

It is a very succint summary of philosophy that explains life.

Kena Upaniṣad

Kenopaniṣad derives its name from the word Kena, meaning 'by whom'. It belongs to the Talavakara Bahmana of Sama Veda and is therefore also referred to as Talavakara Upaniṣad. In short, it says that,
"The One power that illumines everything and every one is indivisible. It is the Ear behind the ears, Mind behind the mind, Speech behind speech, the Vital Life behind life. The ears cannot hear it; it is what makes the ears hear. The eyes cannot see it; it is what makes the eyes see. You cannot speak about it; it is what makes you speak. The mind cannot imagine it; it is what makes the mind think. It is different from what all we know; yet it is not known either. Those who feel they know Him, know Him not. Those who know that anything amenable to the senses is not Brahman, they know it best. When it is known as the innermost witness of all cognitions, whether sensation, perception or thought, then it is known. One who knows thus reaches immortality.

Kathopaniṣad

The Kathopaniṣad is divided into six Vallis. Valli literally means a creeper. A Valli, like a creeper, is attached to the Śakhas or Branches of the Veda. This Upaniṣad is also divided into two Ādhyāyas[1] of three Vallis each. This is one of the most beautiful Upaniṣads, in which the eternal truths are given in the form of a narrative. The narrative is taken from Taittiriya Brāhmana,[2] with some variations. The same story is told in the Taittiriya Brāhmana, the only difference being that in the Brahmana, freedom from death and birth is obtained by a peculiar performance of a sacrifice, while in the Upaniṣad, it is obtained by knowledge only.

Aitareya Upaniṣad

The Aitareya Upaniṣad is one of the oldest of the Upanishads. It belongs to the Aitareya Aranyaka of the Ṛgveda. It is divided into three chapters and contains thirty three verses. This Upaniṣad deals with the process of creation.

Bṛhadaranyaka Upaniṣad

Bṛhadaranyaka Upaniṣad means the "great forest-book". This Upaniṣad is one of the oldest of all the Upanishads. It consists of three sections or kāndas: the Madhu kānda, the Yajnavalkya or the Muni kānda and the Khila kānda. Here the Brahman is portrayed as universal and undifferentiated consciousness. The doctrine of the indescribability of the absolute and the doctrine of 'Neti, Neti' are explained. This Upaniṣad concludes by stating the three virtues that one should practice, i.e. self-restraint, giving and compassion.

Praśna Upaniṣad

In Sanskrit, Praśna means 'question'. This book consists of six questions and their answers, hence the name. It is in a question-answer format. Except the first and last questions, all other questions are actually a group of smaller sub-questions. As narrated in the beginning of this Upaniāad, six pupils interested in knowing divinity or Brahman come to the sage Pippalada and ask questions of great spiritual importance. Pippalada asks them to take up a penance of one year. Upon completion of the penance, they again come to the sage and ask questions, and then the sage answers their questions.

Mandukya Upaniṣad

For the very reason that it explains the esoteric meaning of the fundamental syllable Aum of Hindu spiritual tradition, the Upaniṣad has been extolled greatly. The Muktikopaniṣad, which talks about all other Upaniṣads, says that if a person cannot afford to study all the hundred and more Upaniṣads, it will be enough to read just the Māndūkya Upaniṣad. According to Dr. S. Radhakrishnan, in this Upaniṣad, we find the fundamental approach to the attainment of reality by the road of introversion and ascent from the sensible and changing, through the mind which dreams, through the soul which thinks, to the divine within but above the soul.

Taittireeya Upaniṣad

The Taittireeya Upaniṣad belongs to the Taittireeya school of the Yajur Veda. It is divided into three sections called Vallis. The first is the Siksa Valli. Siksa is the first of the six Vedangas;[3] it is the science of phonetics and pronunciation. The second is the Brahmananda Valli and the third is the Bhrugu Valli. These two deal with the knowledge of the Supreme Self, or 'paramatma-jnana'.

Chandogya Upaniṣad

Along with Brhadaranyaka Upaniṣad, the Chandogyopaniṣad is an ancient source of principal fundamentals for Vedanta philosophy. Considering the number of references made to this Upaniṣad in Brahma sutras, this Upaniṣad is given special importance in Vedanta philosophy. Important spiritual practices like Dahara Vidya and Shandilya Vidya are its specialty.

Mundakopaniṣad

This Upaniṣad begins with an invocation that the eye may see auspicious things, the ear may hear auspicious sounds and life may be spent in the contemplation of the Lord. The teaching of this Upaniṣad is referred to as Brahmavidyā, either because it describes first the message of Hiranyagarbha, the casual Brahma or because the message relates the glory of Brahmam. This Upaniṣad speaks of Brahmavidyā as the mystery which only those with shaven heads and those who go through a rite of having Fire on the shaven head can understand. So, it is called Mundaka, or shaven Head. Apart from this, this Upaniṣad is honored as the crest of all, since it expounds the very essence of Brahma Jnāna. It is assigned to the Fourth Veda, the Atharvana.

Remaining Upaniṣads

The other 98 Upaniṣads are again classified according to their content as follows. They are General,[4] Śaiva,[5] Śaktā,[6] Vaiṣnava,[7] Sanyāsa[8] and Yoga[9] Upaniṣads.
