Sage Sri Ramana Maharishi is right in saying :-
The intricate maze of philosophy of different schools claims to clarify matters and reveal the Truth, but in fact they create confusion where no confusion need exist. To understand anything there must need be the understanding being. Why worry about his bodies, his ahankar, hisbuddhi, creation, God, Mahatmas, world – the not-Self – at all? Why not remain yourself and be in peace?
Take Vedanta, for instance: it speaks of the fifteen pranas, the names and functions of which the student is asked to commit to memory. Will it not be sufficient if he is taught that only oneprana does the whole work of maintaining life in the body? Again, the antahkarana is said to think, to desire, to will, to reason, etc. Why all these details? Has anyone seen the antahkarana, or all these pranas? Do they really exist? They are all conceptual divisions invented by teachers of philosophy by their excessive analysis. Where do all these concepts end? Why should confusion be created and then explained away? Fortunate is the man who does not lose himself in the labyrinths of philosophy, but goes straight to the Source from which they all rise.
Ramana Maharshi says: this self –inquiry is not the critical study of the scriptures. When the source is reached the ego gets merged into it. The result of self-inquiry is the cure for all the sorrows. It is the highest of all the results. There is nothing greater then it. It only indicates there is no necessity to study the scriptures to acquire self-knowledge. (Page-66-practicle guide to know yourself c/e by A.R.N).
Ramana Maharshi says:
Q by D:- Is not necessary to study the Vedas or at least the Prasthanatraya (the Bhagavad Gita,Dasopanishad and Brahma Sutras, all with commentaries)to ensure firm realization?
Ramana Maharshi:-No. Do you need all that to see yourself? All that is intellectual wealth, useful in explain doubts and difficulties if others rise them or if you yourself encounter them in the course of thinking. But to attain realization, all that is not necessary. You want fresh water to drink, but you do not require all the water of the river Ganges to quench your thirst. (Page 111/112 of Practical guide to know yourself c/e by A.R.N).
Why go round and round, by various tortuous paths
When the Vedas and Upanishads declare that Consciousness or Atman is actually nothing but Brahman, then why go round and round, by various tortuous paths, like the blind led by the blind. One has to realize the fact that, the mind is in form of universe. Trace the source of mind and realize that source is consciousness. The mind rises from consciousness as waking or dream and subsides as deep sleep.
Looking at all these facts it makes one clear that, the Self-knowledge or Bramha Gnana or Atma Gnana is main goal of the every human being. Indulging in god and guru glorification is meant for the mass that is incapable of grasping the truth. Thus, people who are capable and have urge to know the ultimate truth or Brahman has to realize the truth is beyond religion, god and scriptures. By glorifying the fake gurus and indulging in rituals one will not be able to overcome the duality, which is mere mirage.
Thus, the goal is to realize Atman ( soul or consciousness). If Atman (soul or consciousness) is nothing but Brahman and by realizing Atman (consciousness) as Brahman (ultimate truth) is truth realization or Self-Realization , then there is no need to follow religion, study scriptures or glorifying gods or gurus and follow the path of doubts and confusion by losing oneself in the labyrinths of philosophy, when there is an easier path. By mentally tracing the source of the mind from where it rises and subsides one becomes aware of the fallacy of the mind, which rises as waking or dream and subsides as deep sleep. The mind raises form consciousness and subsides as consciousness.
