If one is seeking truth but practicing yoga or Kundalini or any other practice for long years and finding them inadequate and useless quenching his inner thirst has to drop them by realizing they are only useful in preparatory stages to make him more receptive to grasp the ultimate truth and they cannot transport him to the ultimate end of understanding.
Seeker has to follow up his deeper self-search and get rid of the inborn samskara or conditioning, which is present as ‘I’ or ‘I AM’. There is no need of buying reading material or hearing the sermons and running to one place to another or one guru to another or surrendering to any guru or glorifying any guru in order to acquire self-knowledge or Brahma Gnana or Atma Gnana.
"Read and be wise" but only if the light of one’s own consciousness awakens the deep-seated understanding is an inherent quality of the soul, the innermost self.
Path of wisdom or Gnana is opposed to common sense because common sense egocentric whereas the wisdom is soul centric. Common sense is habitual and imitative. Common sense is very much required in practical life within the practical world, but in pursuit of truth sharpness to grasp and receptiveness soul centric intelligence attitude is very much necessary.
One can discover these best by considering the terms of praise or blame which are employed in behalf of commonsense. When personal views are condemned as contrary to common-sense is applicable only in practical life within the practical world (realm of duality).
Opinions, views and Judgments based on common sense actual and implied cannot be accepted as ultimate and final because common sense can be applied only in realm of duality.
In pursuit of truth opinions, views judgments derived from commonsense has no value because the common sense is egocentric (form) whereas the ultimate truth is based on soul (formless).
The yogi sees the universe as a second thing and he wants to banish the universe in Samadhi, because he does not know that in nonduality there is no need to deny the universe. But he has to realize the fact that, universe is not something different from the self, which consciousness. Those who cannot grasp and realize this position, misunderstand it, and wrongly hold it be yogic Samadhi where there is only blankness.
The presence of the world, which confronts a Gnani, is not an obstacle to his realization; he does not need yogic Samadhi. But yogi has imagined Brahman as blankness or thoughtlessness thus he is still in the grip of duality. Thus Yogis Brahman is but a thought. Brahman is not a thought but Brahman is prior to any mind or universe. Thus one has to know what is prior to waking experience.
The yogi who wrongly thinks there is Brahman to be got ,may attempt to do so, and may think he sees it, but all the time he under the delusion of duality because he bases his- self on physical body, thinking Brahman to be something different from the soul, which is the true self.
When one becomes aware of the fact all the experiences of the three states and all the thoughts and words are Mind and mind in turn is consciousness then he has transcended thinking faculty
