The Advaitic wisdom of Sage Sankara is a bitter pill. As you start mentally chewing to digest it then it becomes nectar.+

Consciousness is destitute of any other characteristics. Consciousness is without any sort of difference.

Brihadaranyaka Upanishad IV-13:~ As a mass of salt has neither inside nor outside, but is entirely a mass of taste, thus indeed, has that Self neither inside nor outside but is altogether a mass of Knowledge. Just as a lump of salt has inside as well as outside one and the same saltish taste, not any other taste, so also that Brahman has inside as well as outside one and the same intelligence. Inside and outside are mental creations only. When the mind melts in silence, ideas of inside and outside vanish. The sage cognizes one illimitable, homogeneous mass of consciousness only.

The Soul, the Self is present in the form of consciousness, and is all-pervading and unattached. So it is the ultimate truth or Brahman or God in truth.

Srutis emphatically:~ Akasavat Sarvagata Nitya i.e., like ether all-pervading and eternal. If the pot is broken the pot-ether is not in any way affected. So it is unattached (Asanga).

The Soul, the Self is present in the form of consciousness and is Immortal. The nature of the Soul is objectless consciousness.

The Soul, the Self is different from the knowable. The Soul, the Self is beyond the unknowable also. The Soul is incomprehensible. This does not mean that the Soul is a non-entity or void or a negative concept, or a metaphysical abstraction. The Soul is a mass of knowledge or awareness.

Consciousness is denser than stone or platinum or gold. Consciousness is the only real entity, the substratum for everything that exists within the dualistic illusion or Maya.

Advaitic wisdom of Sage Sankara is not tasty, it is a bitter pill. As you start mentally chewing to digest it then it becomes the nectar.

Swami Vivekananda: ~ “Advaita encompasses everything. Since Advaita requires heavy-duty intellectualism, it had to be progressively simplified. (From 'The Complete Works of Swami Vivekananda)

Swami Vivekananda:~ “The wicked are always looking for defects. Flies come and seek for the ulcer, and bees come only for the honey in the flower. Do not follow the way of the fly but that of the bee.

Imparting the Advaitic wisdom to the unprepared mind sent 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 seeker's understanding of ‘what is what ‘grows, gradually the seeker gets a glimpse of truth. Whatever is based on the waking entity is 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 a 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 to reach the ultimate end of understanding. A man of truth will not indulge in the argument he keeps his distance with such a mindset. :~ Santthosh Kumaar
