From the Advaitic perspective, the interpretation of the word is "liberation from ignorance.+

Moksha meaning liberation from the cycle of transmigration pertains to the lower or purely religious sphere. This doctrine is on the lower level because it is based on the reality of form, time, and space. 

From the Advaitic perspective, the interpretation of the word is "liberation from ignorance." Similarly, the word Nirvana is interpreted in Buddhist countries as a means of release from the cycle of births and deaths. This too is the popular interpretation, not philosophical which is precisely the same as the Advaitic perspective. 

It is quite true that Buddha constantly taught that man should seek release from transmigratory existence, but we must remember however that what the sage knows is known only to himself in its fullness and that he gives out to the public only so much as they could grasp and no more. 

Remember:~ 

The history of Advaita is replete with interpretation and reinterpretation of Sage  Sankara’s philosophical work the generation of Advaita followers that succeeded Sage Sankara wrote many commentaries on Sage Sankara’s work each commentator claimed that he grasped the essence and true intent of Sage  Sankara and went on to write according to his own understanding. In that process, he wove into the commentaries, and his personal views and hoisted them on Sage   Sankara. 

This kind of adulation gave rise to several versions of Advaita. The numerous glosses written by his followers tried to blend a ritualistic attitude with the monistic inclination of the Master. The result was the distortion of Sage Sankara’s position. The purpose of the scriptures, Sage Sankara said, was to describe reality as it is. Sage Sankara rejected the Mimamsa view and argued that scripture was not mandatory in character, at least where it concerned the pursuit of wisdom.  

Upanishads, he remarked, dealt with Brahman (God in truth) and that Brahman (God in truth) could not be a subject matter of injunction and prohibitions.

Sage Sankara strongly advocated the study of Upanishads and at the same time cautioned that the study of Upanishads alone would not lead to liberation. In matters such as spiritual attainment, one’s own experience was the sole authority and it cannot be disputed.

Sage Sankara also said the study of Upanishad was neither indispensable nor a necessary prerequisite for attaining the human goal, the moksha.

Sage Sankara pointed out; that even those who were outside the Upanishad fold were as eligible for moksha as those within the fold were.

Sage  Sankara declared that all beings are Brahman, and therefore the question of discrimination did not arise. All that one was required to do was to get rid of ignorance (Duality). :~ Santthosh Kumaar
