Form, time and space are reality within the duality. The duality is unreal in the realm of truth. Whatever prevails without the duality is ultimate truth. Therefore there is a need to know how the duality is unreality in order to know and realize the ultimate truth or brahman.
When one finds diverse contradictions and opinions of beliefs systems, he should reflect that there is some foolishness somewhere. This doubt is the beginning of inquiry into truth.
The religionists says “To believe that one possess truth is not conducive to tolerance". The fallacy is that one presumes to know the truth, as is case of fanatic orthodoxies in all the belief systems. Ignorance and its removal of it by Self -Knowledge or Bramha Gnana or Atma Gnana is the main goal in pursuit of truth.
Those that want ultimate truth or Brahman will not practice control of mind. That is Yoga for the lower web who are not in search of ultimate truth. The seeker of truth will inquire and practice discrimination.
The truth has to be attained not by intuition but by reason, which is superior to it. Not even a combination of intellect and intuition will find truth.
Proof is the first thing in pursuit of truth, if god appears one must be sure what has appeared is god, because all the appearance is mere illusion, on the standpoint of the soul or conciousness or spirit, which is the true self. Religion and Yoga are useful from utilitarian view points, but from point of view of seeking truth they are useless.
In religion there is the element of imagination and speculation. One thinks that religion in which he is born in is better then other religion, which gives him satisfaction, which pleases his taste, and also it is sacred because it is ancient and he has inherited from his forefathers. Such is the limited view of ordinary man. In pursuit of truth seekers have to discards all these type of thinking.
People talk of the peace and satisfaction. What has given one peace and satisfaction is not truth because that peace and satisfaction experienced on the base of physical self(waking entity or ego) is part of the illusion. The illusion is impermanent therefore whatever experienced as peace and satisfaction bound to be temporary not permanent.
Blindly accepting the scriptures without verifying their validity of claims is not allowed in pursuit of truth. One have to look into the facts, for the proof of what has the worship of God done for the people! In the past and present people are being killed in the name of religion and god. Simply to say God saves them is mere speculation: Such an argument is of no value.
Both real and unreal, seen and unseen, trance and activity within the illusion, is created out of the soul or conciousness or spirit, whereas religionists wrongly divorce one from the other. It is absurd to think that anything can be left out of the soul or consciousness.
How can anything be rejected? How can the world be renounced? Only those who delude themselves think so. Everything is soul or conciousness or spirit, and remains so. No name, no form can be given to the soul. Anyone who says he "sees" something within as soul is no Gnani.
When one thinks he is a reflection, a ray of the soul, he thereby separates himself from the soul and imagines an individual soul. Seeker of truth has to give up all these imaginations and speculation and he will find his self to be what it is. To know truth without any doubts, one has to be identical with it, for how can one know what he has got in his mind? Hence duality must disappear.
Reasoning on the true base gives nondualistc or Advaitic truth. Yoga can only lead to temporary happiness. Even the yogic bliss is imagination based on the physical self(ego or waking entity).
The body and universe that one sees is the soul or consciousness because they are created out of the soul or consciousness or spirit. Unless the world is there in one’s realization, ultimate truth cannot be realized.
Ignorance cannot go through merely knowing the soul as self, for it is known in sleep and Samadhi. It can go only by knowing the ultimate truth or Brahman.
