The human soul is a minute part of the universal Soul

" The human soul is a minute part of the universal Soul, and it
feels so limited, so confined, in the physical body that its
greatest wish is to spread out in space and merge with it. And so
it is wrong to think, as people usually do, that the soul is
wholly contained within a human being. No, in reality, only a
very small part of the soul is found within; almost all of it
remains outside and leads an independent life in the cosmic
ocean.
It is important to be clear about the nature and activity of the
soul. So, you should know that the spiritual principle we call
the soul is not enclosed in the physical body. The soul extends
well beyond the physical body, and while it continues to give
life to the body it also travels to visit the furthest reaches of
space and the entities that live there. Our soul is much more
than we imagine it to be: this part of the universal Soul in us
never ceases to reach out into space, immensity, infinity."
