There is no comparison of any other wisdom with Sage Sankara’s wisdom.+

Sage Goudpada: ~ To establish the truth of Non-duality by sheer reasoning alone. He begins by defining "What is real?" "What is unreal?" etc, because that is the right way to discuss or teach. People must first know what they are talking about. (Mandukya Karika)

There is no comparison of anyone's wisdom with Sage Sankara’s wisdom. Without Sage Sankara there is no Advaita. All the Gurus and intellectual version of Advaita is on the dualistic perspective.

Many Gurus describes to perfection is the awakening to Reality ~the realization that pure Consciousness alone is, that the perpetually fluctuating and evanescent contents of the mind derive from it. This awakening effectively happens in an instant. But in order for the lightning flash to take place, resulting in a firm and unshakable certitude, long labor is necessary, which they seem to underestimate. “Truth is formless is their answer.

 Many Gurus' teaching seems essentially negative, potent but bitter medicine for those imprisoned by institutional cults. They break the disciple's bonds but then lead him to a vast desert where they abandon him.

The ultimate state of consciousness they describe is that of the traditional sage or fully enlightened being, but they do not show us the process leading to the realization of this state. They describe marvelously the goal but do not indicate the steps to be taken: their recurring phrases "unified consciousness" and "let go" and "'love alone" are not a roadmap.

Most of the Gurus and Yogis s approach was more practical, and they stuck with the reality of the 'I', they take it as real. All their teachings of Advaita are based on the dualistic perspective. Such teaching will not yield the truth of the whole.

Everyone is not on the same level of understanding. Everyone’s inner work is on. You will slowly steadily but surely be able to understand, assimilate and realize nondualistic or Advaitic truth if you have an intense urge to know the ultimate truth. Because man is egocentric he feels the world in which he is born, lives, and dies is a reality. But when he becomes Soulcentric he realizes his body, his ego and the world in which he exists is merely an illusion created out of the Soul, which is present in the form of consciousness.   : ~ Santthosh Kumaar
