Spiritual Moksha is different for religion propagated Moksha.+

Moksha

The religion propagated Moksha is based on the false self (ego) whereas the Spiritual Moksha is based on the Spirit (Soul).  Spiritual Moksha is diffefromt for religion propagated Moksha.

Religious orthodox think that through their good karma and performing rituals they get moksha. Religious moksha is basethe d on birth entity whereas spiritual moksha is based on the birthless Soul, the innermost Self. 

There are two kinds of audiences - the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of ritual sacrifices, and the more advanced seeker who seeks to know the truth beyond the form, time, and space. The religious orthodoxy is meant for the first audience, to help lead its followers along the way. The Atmic path emphasizes on Advaitic wisdom is meant for those who wish to go beyond form, time, and space. In the Advaita perspective,  moksha is synonymous with the Soul, which is present in the form of the consciousness (Brahman) 

Sruti says "brahmavit brahmaiva Bhavati" ~ He who knows Brahman (Soul) becomes Brahman (Soul) Itself.

Sage Sankara gave religious, ritual, or dogmatic instruction to the populace, but pure philosophy only to the few who could rise to it. Hence the interpretation of his writings by commentators is often confusing because they mix up the two viewpoints. Thus, they may assert that ritual is a means of realizing Brahman, which is absurd.

Arguing with religious believers is fruitless. Belief in tradition and the  scripture as if they were true or factual quite clearly is delusion, but the payoff for holding such delusions is, for those who hold them, extremely compelling ~ the avoidance of the "wrath of God," the hope of heaven or salvation, or the imagined "end of suffering."

"God" exists because “the Self” exist, not vice versa. When awake to true nature then this is known immediately.

That is why Sage Sankara:~  VC- 61. For one who has been bitten by the serpent of Ignorance, the only remedy is the knowledge of Brahman. Of what avail are the Vedas and (other) Scriptures, Mantras (sacred formulae), and medicines to such a one?

Ignorance is the cause of experiencing the world in which we exist as a reality. When you realize the ‘Self’ is you but the ‘Self ‘is the Soul then you will realize the world in which you exist is an illusion.

Whatever is not to happening is happening within the dualistic illusion.   All your happiness and sorrow are a reality within the illusion. Ignorance is the cause of experiencing the illusion as reality. Thus, eradicating ignorance is necessary to realize the truth hidden by the illusory world in which you exist. And this is possible only through Self-knowledge or Brahma Gnana or Atma Gnana.   Thus, there is no other road to freedom other than Advaitic Gnana.  There is no other entrance other than Advaitic Gnana.  The ignorance will vanish only when the Advaitic Gnana dawns.

Many are good at acrobatics with words, but their knowledge is limited to the domain of form, time, and space.  When the inner work is in progress then the realization will happen as the conviction about the Soul, the innermost Self, becomes firm.  

 Sankara, in Bhaja Govindam, says: ~ “(Jnana Viheena Sarva Mathena Bajathi na Muktim janma Shatena)” - one without knowledge does not obtain liberation even in a hundred births, no matter which religious faith he follows.

Self-knowledge or Brahma Gnana or Atma Gnana is universal it does not belong to any particular religion.

Sage Sankara disagrees with Buddhists who say, there is nothing - a nonentity. Sage  Sankara believes there is some reality, even though things are not what they appear to be. If one knows the truth, he will know what to do to find inspiration for action.  The seeker of truth‘s subject is to know what is it that is Real.

Buddhism says:~ All things are illusory and nothing exists.  However, Advaita avers that it is not so.  It says that the universe, of course, is illusory, but there is Brahman (consciousness), that exists forming the very substratum of all things (illusion or universe).

We have to grow from the inside out. None can teach us, and none can make us spiritual. There is no other Guru but our own Soul.”

Self-knowledge or Atma Gnana or Brahma Gnana cannot be attained by one who is without strength or earnestness or without the receptiveness and courage to accept the truth and reject the untruth. If a serious seeker strives sincerely by means of inquiry, analysis, and Soulcentric reasoning, he will be able to realize it.

It is only through seekers' sincerity and earnestness in their spiritual pursuit, that the knowledge started revealing on its own.  Anyone who has humility and patience and is sincere and ready to drop their accumulated dross and receptive to accept the truth will enter Self-Awareness when his conviction becomes firm.  : ~Santthosh Kumaar
