Muktikā (Sanskrit: मुक्तिका) refers to the [[ SANSKRIT language anthology of a canon of 108 Upaniṣhads. 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.
Muktikā refers to the collection of 108 Upanishads available in printed form since 1883 CE in the Telugu language. The canon is part of a dialogue between Rama and Hanuman dealing with the inquiry into mukti in the Muktikā Upanishad (108 in the list). The other collections of Upanishads include Oupanekhat, a Persian language anthology of 50 Upanishads; the Colebrooke Collection of 52 Upanishads, and the 52 Upanishad Collection of Nārāyana.
The canon is part of a dialogue between Rama and Hanuman. Rama proposes to teach Vedanta, saying "Even by reading one verse of them [any Upanishad] with devotion, one gets the status of union with me, hard to get even by sages." Hanuman enquires about the different kinds of "liberation" (Mukti, hence the name of the Upanishad), to which Rama answers that "the only real type [of liberation] is Kaivalya".
But by what means is the Kaivalya kind of Moksha got? The Mandukya is enough; if knowledge is not got from it, then study the Ten Upanishads. Getting knowledge very soon, you will reach my abode. If certainty is not got even then, study the 32 Upanishads and stop. If desiring Moksha without the body, read the 108 Upanishads. Hear their order. (trans. Warrier)[full citation needed]
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:
The Vedic texts were orally composed and transmitted, without the use of script, in an unbroken line of transmission from teacher to student that was formalized early on. This ensured an impeccable textual transmission superior to the classical texts of other cultures; it is, in fact, something like a tape-recording.... Not just the actual words, but even the long-lost musical (tonal) accent (as in old Greek or in Japanese) has been preserved up to the present.
The first 13 are grouped as mukhya ("principal"). 21 are grouped as Sāmānya Vedānta ("common Vedanta"). The remainder are associated with five different schools or sects within Hinduism, 20 with Sannyāsa (asceticism), 8 with Shaktism, 14 with Vaishnavism, 12 with Shaivism and 20 with Yoga.
