The marginal living entities (jiva-souls) exist for infinity.

What happens to jiva-souls (like us) who have chosen to remain in this temporary decaying material world?

Someone in a class today asked what happens to the jiva-souls if they do not serve the Spiritual Master and Kṛṣṇa and return back home, back to Godhead but instead choose to remain in the material world's cycle of birth and death?

Most of us cannot comprehend that the jiva-souls have ALWAYS existed for infinity! For eternity! That means without having a beginning point, nor will there be an ending point.

The implications of actually realizing this is are mind blowing.

One does not become rich and famous by chance, it is earned over billions of life times where the jiva-souls must accumulate the pious or impious activity so they can fulfil their desires, and be trained up by material nature to be qualified to possess a material bodily vessel like Bill Gates, Paul McCartney, Mark Zuckerberg, Elon Musk, Stalin, Hitler, etc etc, every jiva-soul only gets exactly what they deserve.

Fulfiling every desire is therefore possible on the stage of eternity. 

The implications of never dying (only the material vessel breaks down, decomposes and dies) is ignored by most human beings,  most cannot get their head around the fact there really is no death, as spiritual beings we just go on and on and on and on changing material bodily vessels for eternity.

The jiva-souls exist for infinity, meaning, just like Krsna, they are beginningless and endless and were NEVER created.

Bhagavad Gita As It Is - "Never was there a time when I did not exist, nor you, nor all these kings; nor in the future shall any of us cease to be." (BG, Ch 2 Text 12)

Bhagavad Gita As It Is - "For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal, ever-existing and primeval. He is not slain when the body is slain." (BG Ch 2 text 20 "corrected" edition)

So there is no such thing as new jiva-souls being created because they have always been and were NEVER created.

Srila Prabhupada – "There are no new souls, new and old are due to this material body, but the jiva-soul is never born and never dies, so if there is no birth, how can there be new souls?" (Letter to Jagadisa dasa, 7/9/1970)

Only matter is temporary (like the material bodily vessel the jiva-soul is presently in), while the jiva-souls in the material body are eternal and can NEVER cease to exist.

This means when the material vessels the jiva-soul is in, breaks down due to disease, decay or accidents, and ceases to function, also due to old age, the jiva-soul can no longer remain in that broken material body, and is forced to take another body in the womb of a new mother.

Actually, getting a human body in the material world is very rare and in most cases one’s next birth is in the lower species of life, where the jiva-soul must evolve through the species of life to they again reach the human platform.

This process has been going on for infinity which means the jiva-souls have probably experienced every material bodily existence imaginable already because this process has no beginning.

The consequences of ♾️ (infinity) is mind blowing, but there is a way out of this temporary (eventually repetitive) material manifestation.

In other words, if you stick around long enough in the material world, the combinations of material elements will begin to repeat themselves.

However, the real cause of remaining in the material manifestation within the endless cycle of birth and death, is self-centred “desire.”

The goal of a Vaiṣṇava is to get out of this temporary decaying material existence and return back home back to Godhead.

To enter the perpetual Vaikuntha planets to be with Visnu, or enter Goloka-Vrindavana and be with Krsna, where one is no longer covered by a nasty material bodily vessel, and ARE instead fully their spiritual body, never again to experience death.

There is a way out of this material world and it begins by chanting Hare Krsna and finding a bonafide spiritual teacher.^^.
