The knower, knowledge and the known are one in essence

Burden implies the existence of something apart from oneself, thus it is part of the duality. The duality persists after non-dual Realization but not as reality, there is no ignorance after realization of the self.

There will be no burden of duality in the absence of ignorance. On the other hand, the burden and bondage will not cease so long as duality experienced as reality. Therefore when one become fully aware of the fact that duality is unreal the burden also becomes part of that unreality.

What is perceived as waking or dream  is apart from the Self is also clearly seen to be perishable. What is perishable must certainly involve fear of loss. Union implies separation; so also acquisition implies loss.

If emancipation be external to the True Self (soul or consciousness), it implies fear of loss, and is therefore not worth aspiring to. On the other hand, freedom is fearlessness and not external to the Self.

"When the knower, knowledge and the known merge into unity then  that state is totally free from burden and bondage of duality  and hence freedom results. Non-dual Wisdom is the state devoid of duality, and is unimpeded by ignorance.

It is certainly the primal state of the knower, but remains unrecognized for want of acquaintance with it. The F.P blogs are signposts. The inner  guidance alone can make the individual acquainted with the true Self.

The soul the innermost self is  free from  experiencing duality as reality. The knower, knowledge and the known are not real as different entities. The knower, knowledge and the known are one in essence. When differentiation among them is destroyed, their true nature is evident in the resulting non-dual awareness, which is also the state of emancipation.

There is in fact no differentiation among the knower, etc. The differences are simply conventions retained for the smooth working of metrelistc life. Emancipation is eternal and, therefore, here and now, it is nothing to be acquired in the next life and next world. 

The consciousness, the innermost  Self  manifests as the knower, knowledge and the known; the cycle of births and deaths endures with all the apparent reality of the world as long as waking or dream lasts. As soon as the manifestation is realized to consist of the formless  Self alone without any admixture of non-self, the waking or dream [cycle of births and deaths] comes to a standstill, and is melted down to water like snow melts by the summer sun.

Thus earnestness is the only requisite for emancipation. No other requisite is needed if the longing for emancipation is intense and unwavering. There is the use of efforts in the absence of a real and unswerving desire for emancipation that is the sole requisite and nothing else.

Intense urge signifies mental abstraction as the seeker loses himself in the desired goal. Unwavering zeal must certainly succeed and success is only a question of time - which may be days, months, years, according to the seekers receptivity and sharpness to grasp.
