How is this self realization (complete knowledge of 84 births) going to occur or in other words what is the process that any soul will have to pass through to achieve this self realization?
This self realization should be based on the formula given in Gyan. It is a systematic process that each soul will pass through to attain this self realization. The number one soul (Soul of Ram) will catch hold of this subtle process first and attain the self realization first of all in this world. Then, it will be number wise for others.
This self realization is partially dependent on the shooting that the soul is undergoing in this new birth as a Brahmin. The subtle shooting of thoughts, words and action that the soul is going through currently in the shooting period does reflect the part of the soul in the broad drama.
Another important point here is that as much as one remains in the nirakari state (incorporeal/soul conscious state/seed stage), more and more one will travel further towards complete self-realization. So, this effort to remain in nirakaari stage is also number wise. Number one soul (soul of Ram) will be more nirakari compared to the number two and so on.
Toh is cchotein sein Sangamyug ke aloukik jeevan, aluokik praptiyaan, aloukik anubhav ko dwapar sein bhakton ne bhinna bhinna naam sein yaadgaar banaa diye hain. Ek janma ki aapki yah jivan, Bhakti ke 63 janmon ke liye Yaad kaa saadhan ban jaati hain, AV Vani 7/3/86.
So, the acts that a soul performs in Sangamyug, the method of remembrance that the soul adopts,extent of God consciousness that the soul develops and all the efforts made by the soul in Sangamyug to become soul conscious will be repeated by the soul in the 63 births of "Bhaktimarg" from Dwaparyug. And whatever is done in the past 63 births by a soul, will certainly appear in front of the soul or will be repeated by the soul in just one birth of the Sangamyug, i.e. the soul will repeat all the 63 births of the past Bhakti in just one birth of Sangamyug.
This subtle Bhakti of 63 births will not be considered to be over until the soul becomes constant and complete soul conscious which is equivalent to the start of the so called 21st birth of Swarg or 1st birth out of the 21 births in Satyug and Tretayug because swastithi sein bantaa hain swarg aur par-stithi sein banta hain nark. So, "bani banaayee ban rahee abh kuch banni nahi"
