Thus the seekers main aim is to mentally trace the formless substance of the illusion, which is also the witness of the illusion. The formless substance and witness of the illusion (world) is the Atman, and this Atman itself is Brahman.

YOGA VASISTA: The greatest Gnani: “His state is indescribable yet he will move in the world like anybody else," ..."Though acting after every feeling such as love, hate, fear and the like, he who stands unaffected within is said to be real jivanmukta." Sankara's commentary.

Yoga Vasista says of the Gnani: "He is a great worker." It also so says, that he keeps his body healthy, does not starve it.

The essence of Mandukya is: Do not be satisfied with rituals, yoga etc. which are good in their own way, but inquire. Into what? Brahman and Atman are things you can never see. So do not inquire into them. Inquire into the world around you, which you can see. Science tells you it is passing away every second. Everything is dying repeatedly. Where is it going? Thus you follow up your inquiry into what you can lay hands on. How can you inquire into Atma which you cannot see? So first we deal with the known and seen, this inquiry leads up to the unknown in the end. 

The soul  is unborn, the soul  is eternal.   in  the realm of ultimate reality there is   no duality, no likes and dislikes. There is no second thing exist other than awareness of the soul, the innermost self.  If this is perceived, than it is ultimate reality or Brahman.

Wisdom  does not  arise  by bathing in the holy rivers, nor by a doing Kriya yoga Pranayama nor  hata yoga nor control of the vital force nor by glorifying gurus.

Success depends essentially on a qualified aspirant; time, place and circumstances and other such means are but auxiliaries in this regard.

The seeker after the truth should take to soul centric reasoning and discriminate between dual and non-dual experiences to realize 'what is  truth' and 'what is untruth'.

The seeker who has intense urge in knowing the truth and sharp in grasping, skillful in understanding and assimilating without the scriptures, the one who has got these characteristics is the fit recipient of the self- knowledge or Brahma Gnana.

According to Sankara, it is the ignorance of our real nature that causes suffering and pain. The desire for happiness is essentially a longing to awaken to who and what we truly are.

When Sage Sri, Sankara says the world is illusion, it includes birth, life and death, which happens within the world.  Thus the seekers main aim is to mentally trace the formless substance of the illusion, which is also the witness of the illusion. The formless substance and witness of the illusion (world) is the Atman, and this Atman itself is Brahman.

 This Brahman cannot be attained by indulging in egocentric religious orthodoxy.

The knower of Brahman is Brahmin not the Brahmin who indulges in priest craft, which leads one to utter darkness as per Yajur Veda.

Brahmin is the one who has realized the Brahman (ultimate truth) and helps fellow seekers towards inner path. The one who knows Brahman knows his body and his experience of the world are mere illusion and also he knows his body and his experience of the world are also as Atman (consciousness), which is Brahman.  Thus, the priest craft which are crafted on the body based theories will lead one to hallucinated Moksha  But real Moksha or freedom is possible only through non-dualistic or Advaitic  wisdom. 

Thus it is necessary to follow the path of Brahman not the path of the orthodox priest- craft. Only by   dropping all the accumulated priest crafted baggage, one has to move forward to reach the non-dual destination in lesser time and effort.
