What are Upanishads?
Before knowing Yoga Upanishads, Let us see what are Upanishads. They are the highest wisdom of mankind. Additionally, they are the very essence of the Vedas. In the words of Sri Aurobindo, they are the supreme work of the Indian Mind and a record of the deepest spiritual experiences.
On the tree of Indian wisdom, there is no fairer flower than the Upanishads and no finer fruit than the Vedanta philosophy.-Paul Deussen, Outline of the Vedanta System
It is a common belief that each Upanishad contains at least one hidden doctrine. Most of the Upanishads are in the form of a dialogue between a disciple and Guru or God. At the request of the disciple, the Guru clears the doubts of the disciple by way of discourse on a specific religious dogma. Hence, the Upanishads are the spiritual teachings of the enlightened.
The Sanskrit term Upanishad means sitting near or under. Upa=near, and shad=to sit. Hence the term refers to Sitting near or under the enlightened to get wisdom.
Monier-Williams Sanskrit English Dictionary gives some other interpretations: ‘setting at rest ignorance by revealing the knowledge of Supreme Sprite; the mystery which rests underneath the external system of things; esoteric or secret doctrine’.
The Vedas have four sections: Samhitas, Brahmanas, Aranyakas, and Upanishads. Upanishads are the concluding part of Vedas or simply Vedanta.
Number of Upanishads
There are more than two hundred Upanishads available today. Of them, ten Upanishads are the most important ones. They are Mukhya (important) Upanishads and Adi Sankara wrote commentaries for eight of them. They are the earliest of the Upanishads and pertain to a period well before the 3rd Century BCE. Other Upanishads belong to the later periods.
In Muktika Upanishad is a tutelage of Lord Rama to Lord Hanuman. It gives an index of 108 Upanishads. The composing period of Upanishads ranges from the 10th Century BCE to the 14th century CE. In the 18th Century CE, Sri Ramachandrendra Sarasvati by his cognomen name Brahma Yogi wrote commentaries for all 108 Upanishads.
