One sees all men and the world within the waking or dream

Scriptures are the experience only of the few; hence it is only individualized truth. Reason and universal experience must take precedence over it and over hearsay in the quest of ultimate truth regarding the three states. No scripture can help in pursuit of truth. People will be prejudiced by this man's or that man's view.

There are unfortunately so many different kinds of Yoga. But no yogi uses reason based on the soul. Yoga means killing reason, thus it is no use in to acquire non dual wisdom. Yoga is good as a preparation only.

Many People want to take as less trouble as possible and gain as much as possible. They disdain the hard labour of thinking needed in pursuit of truth and hope to get truth by doing nothing i.e. merely believing or refraining from thought in yoga.

Conversion can occur only in the sphere of religion, never in pursuit of truth. When one knows non dualistic or Advaitic  truth, he becomes free from sphere of imagination

If one’s reason is not sharp enough, then only religion and yoga can satisfy him. The seeker of truth examines both scientific and religious doctrines and discoveries and to evaluate them.

"All men are mortal" because they exist within the illusion (waking or dream). One sees all men and the world  within the waking or dream. If there is no waking or dream then there are no men and the world. Man exists within the waking  or dream and imagines on the base of physical entity or ego which is limited only to waking experience.

As logic is built upon more imagination, as assumptions, therefore it is no path to non-dual truth. It is like religion and mysticism. One postulate certain things and show they agree with others that he has already taken for granted. This is called the "coherence" theory of truth. But it is fallible.

When one trying to get rid of thinking in yoga he cannot get any truth. Thinking is a main tool in pursuit of truth. When anyone avoids thinking, runs after religion and yoga, he may be sure that they do not want to be troubled by effort to think.

Science stops in midway, if went to the very root; it would get non -dualistic  truth. All this science helps to make the reason clear, sharpens the mind, but it will take centuries for them to go to the very root.

Theology is based on imagination; scholasticism upon logic. The non-dual truth can be got only inquiry analysis and reasoning on the true base and not by millions of karmas (actions) as scriptures declare. Since man, world and universe is part and parcel of the illusion. Therefore, the karma based on the false self within the false experience is no use. It is unfortunate that people agree the body is not the self, but they refuse to accept the fact that the karma theory is based on false self ( waking entity or ego)  since they are still slaves of their samskara or  conditioning.

In Isa Upanishad says:

MANTRA 10

Avidya is Karma and therefore a hindrance. You perform Avidya - i.e., you perform Agnihotra and other sacrifices. This is a roundabout way of purifying the mind, and it is also groping in the dark. But it may not have as heavy a toll on your time and energy as the other.

Since ignorance is karma. And karma is possible only in ignorance. Therefore, the three states are reality only on the base of false self. Thus, whatever actions and conducts performed on the base of false self, with in the false experience, is bound to be false-hood. Thus the karma theory based on the false self has to be false theory.

One must deal only with the facts of experience, not of imagination.
