Muktikā


The Muktikā refers to the canon of 108 Upaniṣads. The date of composition of each is unknown, with the oldest probably from about 800 BCE. The Principal Upanishads were composed in the 1st millennium BCE, most Yoga Upanishads composed probably from the 100 BCE to 300 CE period, and seven of the Sannyasa Upanishads composed before the 3rd century CE.

The Canon

The canon is part of a dialogue between Rama and Hanuman. Rama proposes to teach Vedanta, saying "Even by reading one verse of them with devotion, one gets the status of union with me, hard to get even by sages." Hanuman enquires about the different kinds of "liberation", to which Rama answers that "the only real type is Kaivalya".
The list of 108 Upanishads is introduced in verses 26-29:
Some scholars list ten as principal – the Mukhya Upanishads, while most consider twelve or thirteen as principal, most important Upanishads.

    Transmission

Almost all printed editions of ancient Vedas and Upanishads depend on the late manuscripts that are hardly older than 500 years, not on the still-extant and superior oral tradition. Michael Witzel explains this oral tradition as follows:

Categories

In this canon,
The first 13 are grouped as mukhya. 21 are grouped as Sāmānya Vedānta,
The remainder are associated with five different schools or sects within Hinduism, 20 with Sannyāsa, 8 with Shaktism, 14 with Vaishnavism, 12 with Shaivism and 20 with Yoga.
Krishna YajurvedaAtharvavedaSamaveda
Mukhya;
these form the core of ancient texts, predating classical Hinduism; they span the 1st millennium BCE and reflect the emergence of Vedanta from Vedic religion.
