Upanishad:~ “They alone in this world are endowed with the highest wisdom who are firm in their conviction of the sameness and birthlessness of Atman.+

There is no Advaitic wisdom without Sage Sankara. All the 'I-centric' Gurus and their teachings are not the Advaitic wisdom of Sage Sankara.

When Advaitic Sage Sankara has given the clear-cut instruction to acquire Self-knowledge or Brahma Gnana or Atma Gnana, then why waste time with other Gurus teaching and their instruction?

The seeker need not follow any religion or study the scriptures or glorify the Gods and the Gurus, or by practicing yoga or by losing himself in the labyrinths of philosophy to acquire Self-knowledge or Brahma Gnana or Atma Gnana.

Upanishad:~ “They alone in this world are endowed with the highest wisdom who are firm in their conviction of the sameness and birthlessness of Atman. The ordinary man does not understand their way.

Upanishad says: ~ The human goal is to acquire Self-Knowledge, and they indicate that belief in the personal Gods, yoga scriptures, worship, and rituals are not the means to Self-knowledge, then why should anyone indulge in it.

The religion, concept of individualized god, and scriptures are the greatest obstacles to realizing non-dual truth or Self-realization because they are based on the false self.

The seeker of truth has to search for the ultimate truth without losing himself in the labyrinths of philosophy, through deeper Self-search and assimilate, and realize it.

That is why Sage Sankara, indicated 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.

Sage Sankara said:~ Talk as much philosophy as you like, worship as many gods as you please, observe ceremonies, and sing devotional hymns, but liberation will never come, even after a hundred aeons, without realizing the Oneness.

Only through deeper self-search, beginners and intermediates gradually become aware of ‘what is what’. Only after they have realized the fact that the Self is not ‘I’ but the Self is the invisible Soul, which is present in the form of consciousness, they are ready for the inner journey towards reality, which is beyond form, time, and space.

That is why Sage Sankara says: ~ there is no need to study the Scriptures, in order to realize the ultimate truth or Brahman.

~ then why indulge in studying the scriptures?

Sage Sankara says: ~ there is no need to study philosophy, in order to realize the ultimate truth or Brahman.

~then why indulge in studying philosophy?

Sage Sankara says: ~ there is no need to indulge in rituals, to realize the ultimate truth or Brahman

~then why indulge in rituals?

Sage Sankara says: ~ there is no need to indulge in yoga, to realize the ultimate truth or Brahman

~then why indulge in yoga?

Sage Sankara says the transparent Truth of the Self, which is hidden by the illusion, is to be attained through the instructions of a knower of Brahman (Gnani)

~ then why stick to a Guru who is not a Gnani?

Sage Sankara: ~ VC Neither sacred baths nor any amount of charity nor even Hundreds of pranayamas* can give us the knowledge about our own Self. The firm experience of the nature of the Self is seen to proceed from inquiry along the lines of the salutary advice of the wise. (13)

Sage Sankara says ~ “The exercise in discrimination between real and unreal and renunciation of the false is real meditation, then why are you indulging in other types of meditation.

Sage Sankara: ~ VC~ "All this universe, which through ignorance appears as of diverse forms, is nothing else but Brahma, which is absolutely free from all the limitations of human thought.

Sage Sankara says you must first know what is before you. If you cannot know that, what else can you know or understand? If you give up the external world in your inquiry, you cannot get the whole truth.

Sage Sankara says: - VC-65. As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent truth of the Self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman.

People refuse to accept anything other than their Guru's words. For them, their Guru's words are the ultimate truth. They do not accept anything other than their accepted truth. There is no need to convince such a mindset.

Such mindsets are not fit to acquire Self-knowledge or Brahma Gnana, or Atma Gnana. The seekers of truth accept only the truth, nothing but the uncontradictable truth.  : ~ Santthosh Kumaar
