Imparting the Advaitic wisdom to the unprepared mindset would be ‘equivalent to giving sermons to the stone statues.+

Advaita is universal. Advaita is not for sale. Do not buy Advaita from the spiritual supermarket. Advaita is the nature of the Soul, the innermost Self. The world in which you exist is created out of single stuff. That single stuff is consciousness. Knowledge of the single stuff is Advaitic wisdom. 

Advaitic truth is very simple, but it is very difficult to realize because you have accumulated mental garbage from different sources in the name of Advaita. Until you discard all the accumulated knowledge you will never be able to realize the Advaitic truth, which is beyond the form, time, and space. 
The Advaita is the nature of the Soul, the 'Self' shines on its own awareness when wisdom dawns. 

The Advaita is the Soul is the cause and the support of all that exists in the world in which we exist. Advaita is the nature of God, the innermost Self. 
The Advaita is present in the form of consciousness. Advaita is the root element of the universe. From the Advaita, the universe comes into existence. In the Advaita, the universe resides. And into the Advaita, the universe is dissolved. The Advaita is the parent of all that is there.

Katha Upanishad says:~ Fools dwelling in darkness, but thinking themselves wise and erudite, go round and round, by various tortuous paths, like the blind led by the blind. (Ch~ II-5 P-14)

Those who indulge in the perverted argument from their own standpoint and opinion are not seeking the truth, which is beyond form, time, and space.  They just want to exhibit their accumulated knowledge accumulated from here and there.  They think what they know is the ultimate truth.

They think whatever they propagate is the ultimate truth. The question never occurs to them, “Is what I know really the truth?:

Those who assert the world is reality are still in the elementary stages of the preliminary analysis. The world is a reality within the waking experience, but the waking experience is merely an illusion. In the same way, the dream world was a reality within the dream experience. The dream became unreal when the waking took place. In the same way, the waking becomes unreal when Advaitic wisdom dawns.
Remember:~ 

When the Self is not you, but the Self is the Soul. The yoga is based on you. You are the false self within the false experience. The Soul is the Self. The Soul is present in the form of consciousness. If the Self is not you then what the use of arguing about yoga is, which is based on the false self (you) within the false experience (waking).

A person, who stamped his foot on the ground to refute to show the world, is real, ignores that in a dream he would do exactly the same--stamp his dream foot on the ground and assert it to be real. 

Imparting the Advaitic wisdom to the unprepared mindset would be ‘equivalent to giving sermons to the stone statues.

Everyone is not ripe enough to understand and assimilate the Nondualistic or Advaitic truth. Some people want to exhibit their intellectual wealth, but it has no value in the pursuit of truth.

The seeker must have enough patience, humility, and an intense urge to know the truth. Arguments and provocation will not yield truth. Perfect understanding of ‘what is what ‘leads to the realization of Nondualistic or Advaitic truth.

As the seekers' understanding of ‘what is what ‘grows, gradually the seeker gets a glimpse of truth. Whatever is based on the waking entity is a falsehood and whatever is based on the formless Soul, the Self is real and eternal. 

Thus, it is necessary for the seeker of truth to make sure the waking entity (ego) is not the Self but the Self is formless Soul in order to acquire Self-knowledge or Brahma Gnana or Atma Gnana.

The seeker has to have an inner urge to know the truth seriousness, patience, and humility in order to reach the ultimate end of understanding. A man of truth will not indulge in an argument he keeps his distance with such a mindset. :~Santthosh Kumaar
