In that epoch sages and seers sought to convey complex philosophical and metaphysical concepts to their disciples and lay folk through parables, similes, analogies and metaphors. The idea of Brahman was conveyed through numerous metaphors that became popular and are used to this day.

In my view the most apt metaphor explaining creation and immanence is that of the spider which spins out silken threads from its body and creates a web after which it goes and sits at it heart much like Brahman creates the phenomenal world and enters it:

”Just as the spider pours forth its thread from itself and takes it back again; just as herbs grow on the earth and hairs from living man, even so the universe grows from the imperishable” – Katha Upanishad

” Just as there shoot out from a blazing fire sparks by the thousands, resembling the fire, so do the various beings ( or states: bhava) proceed from that imperishable; and into It, verily, they return.” – Mundaka Upanishad

” Like the butter hidden in milk, Pure Consciousness resides in every being. It is to be constantly churned, with the mind serving as the churning-rod” – Amrtabindu Upanishad

Two Birds on One Tree Metaphor:

” Two birds close companions, reside in intimate fellowship on the same tree. One of them eats the sweet fruit of the tree; the other, without eating, watches”. – Mundaka Upanishad

The bird that eats the fruit is the individual personality, the tree is life and  the one that watches is the soul an aspect of Brahman.
