Human beings have descended from the heavenly regions

"Human beings have descended from the heavenly regions through a
process known as involution. During this descent into matter, as
they drew further and further away from the primordial fire they
took on bodies of increasing density, right down to the physical
body, just like in winter, when we are faced with the cold and
have to wear increasingly thick clothing, from a vest and shirt
through to an overcoat!
Now, on the way up again, human beings must undress,
symbolically speaking, that is, strip away anything that weighs
them down: instead of seeking to amass, they must learn to
renounce, cut loose and free themselves. Amassing encourages
descent. Any thought, feeling or wish inspired by the instinct to
possess clings to the subtle bodies like frost clinging to the
branches in winter. The spring sunshine has to return so that the
frost can melt and humans can recover their true being."
