Not one of this can explain the ultimate reality completely, but then we use multiple analogies together.
From Mundaka Upanishad 1.1.7:
yathorṇanābhiḥ sṛjate gṛhṇate ca yataḥ pṛthivyām oṣadhayaḥ sambhavanti yathā sataḥ puruṣāt keśalomāni tathākṣarāt sambhavatīha viśvam
- Spider weaving web (flaw: spiders can leave web)
- Herbs growing on earth
- Hair growing on humans
Also, spiders use will, while the other two don’t.
Unverified
Clay Pot analogy
Chaandogya Upanishad 6.1.4-6.1.7:
vācārambhaṇaṁ vikāro nāmadheyaṁ mṛttiketyeva satyam
All transformations are just names based upon speech; the clay alone is real.
Gold Ornaments Analogy
Brihadaaranyaka Upanishad 2.1.9:
yathā ha vai lohamayaṁ karaṇam nipuṇena kartṛṇā vibhajyamānaṁ nānā-rūpaṁ bhavati
Ornaments made from gold – they may appear different, but are all gold.
Hot Rod - Flame Analogy
Prashna Upanishd 5.5’s Shankara Bhashya:
yathāgniḥ ekadhā arciḥ…
Iron rod in fire glows like fire but is still iron – a metaphor for jīva appearing as Brahman.
Water-Waves Analogy
This is more common inAdvaita texts like Viveka Choodaamani, Drg-Drishya Viveka, Panchadashi, but its seed ideas are found in Shruthi:
Chaandogya Upanishad 7.23.1
sa eṣa neti netyātmā…
implies the formless substratum, akin to water-wave analogy)
Ṛgveda 1.164.46:
ekam sat viprā bahudhā vadanti
Dream and Waking States
Brihadaaranyaka Upanishad 4.3.9
sa yathā swapne mahārājā bhavati…”
The Self creates its own world in dream—suggesting māyā and projection
Similar to Maandookya Upanishad 3-7 (analysis of Avasthas)
Reflections
Also found in Viveka Choodaamani.
Brihadaaranyaka Upanishad 2.5.19
Also in Katha Upanishad 2.2.9
yathā dīpo nivāta-stho…
(not the same analogy, but a metaphor for the subtle Self)

From Texts Directly
Aithareya Upanishad says, ‘He thought I shall indeed create the world.’
Thaitthireeya Upanishad states ‘He desired I shall become and be born. He performed Tapas. Having performed Tapas, He created all this whatsoever we perceive.’
Prashna Upanishad says Prajaapathi, having performed penance, created a pair - Rayi, matter and Prana, energy - thinking that they would together between themselves produce creatures in many forms.
Katha Upanishad says the whole Universe, evolved from the Brahman, moves or vibrates in the Prana meaning thereby that creation is a motion, a vibration of energy.
Mundaka Upanishad says from the Brahman are produced all these: the Creator, names and forms and nourishment for all.
Chaandogya Upanishad says that in truth, this many seeming world is only one Reality, in which all things seem to be born, seem to live and pass away.
Shvetaashvatara Upanishad uses a simile to explain the process of creation. Just as a ray of light, though colorless in itself, assumes different colors when it passes through a prism, the formless Brahman who is one without a second, who is undifferentiated - nirvisesha, for the reasons not known to the human mind, created diversity at all levels with the help of His own power. When the world meets its end, all these diversities merge back unto Him.
Brhad-Aranyaka Upanishad gives a detailed account of how the One, Brahman became many - all the elements and the pairs of male and female.
Maithri Upanishad tells us that the three worlds, Bhuh, Bhuvah and Svah, are the very gross forms of Prajapati.
Paingala Upanishad mentions the famous process of quintuplication - panchikarana - or splitting and mixing up of subtle elements in various proportions to make them gross substances out of which Prajapati created many Brahmandas - macrocosms and many worlds appropriate to each of them - microcosms.
Brahma Soothras which interpret and organise the Upanishads, regard Brahman as the material as well as the efficient cause of the universe, its origin and support, himself uncreated and eternal.
Bhagavad Geetha
The gist of chapters 7, 9 and 15 of the Geetha which deal with this topic is that all the physical elements of nature, including the material bodies of animate beings and their sensory and mental functions, may be grouped together forming the ever changing physical aspect of the universe. This is called Prakrti.
Behind the living is the soul that dwells within each being and animates it. Behind all again is the Supreme Being whose power holds together all the changes visible in one organic existence. He dwells within, supports and moves everything, but exists apart from all.
The Absolute is the universal soul or Purusha of which the whole Prakrti or nature is an outward manifestation. The universe moves according to what are known as the laws of nature. This code of nature is nothing but the manifestation of the Supreme will. Life proceeds as if wholly independent of God.
Bhagavan says ‘Reflect on this that as the mighty air everywhere moving is yet fixed in space, even so all beings, are dependent on me’.
