Where can I find upanishad's verse in vedas?

Question

Upaniṣads are the part of vedas. Is it possible to find the verse of upanishad in vedas.

For example :

Bṛhadāraṇyaka Upaniṣad

Chapter I > Section IV - The Creation and Its Cause

In the beginning, this (universe) was but the self (Virāj) of a human form. He reflected and found nothing else but himself. He first uttered, ‘I am he.’ Therefore he was called Aham (I). Hence, to this day, when a person is addressed, he first says, ‘It is I,’ and then says the other name that he may have. Because he was first and before this whole (band of aspirants) burnt all evils, therefore he is called Puruṣa. He who knows thus indeed burns one who wants to be (Virāj) before him. (1.4.1)

Can anyone give the same verse but from vedas. Like rigveda 1:4:1 (just an example).

basically my question is "Where can I find upanishad's verse in vedas as it is a part of vedas"

Answer 1

You can find Samhita verses in Vedas. I will limited examples from this blog of Ram Abloh Ji a great Vedic Scholar. Please read his blog.

I was Manu and the Sun. I am the wise Kakṣīvān Ṛṣi. I nurture the white bolt of lightning (or the Ṛṣi Kutsa). I am the ancient Kavi Uśanā. O people, look at me! (i.e. you can also become enlightened like me) (RV 4.26.1)

Having realized this truth, the Ṛṣi Vāmadeva declared “I was Manu and the Sun” (Br Up 1.4.10)

O Agni, lead us on the right path as you O Lord are omniscient. Destroy this stubborn sin from us, we bow to you profusely.(RV 1.189.1)

O God Agni, lead us on to prosperity by a good path, judging all our deeds. Take away ugly sin from us. We shall say many prayers unto thee.(Isa Up 18)

Two birds of beautiful feathers, very attached to each other, best friends, sit on the same tree. Of them, one eats a tasty fruit, and the other watches silently without eating(RV 1.164.20)

Two birds of beautiful plumage, who are inseparable friends, reside on the self-same tree. Of these, one eats the fruits of the tree with relish while the other looks on without eating.(Svet Up 4.6)

The Omniscient One (Jātavedā) is well-hidden in wood (or bodies) just as an embryo is well-hidden in the womb of the pregnant. Agni is to be worshipped everyday by the awakened (i.e. enlightened), offering human beings.(RV 3.29.2)

The fire lodged in the aranis, as the foetus is well-borne by the pregnant woman fit to be worshipped every day by watchful offerers and other men. This verily is that.(Katha Up 2.1.8)

The Universal Person has a thousand heads, a thousand eyes and a thousand feet. He envelops the earth all around but stays above it by a measure of ten fingers .( RV 10.90.1)

That Infinite Being has a thousand heads, a thousand eyes and a thousand feet enveloping the whole universe on all sides. He exists beyond ten fingers.(Svet Up 3.14)

The Universal Person is indeed all this, whatever was, and whatever will be. He is the Lord of Immortality, and he grows by food.(RV 10.90.2)

That which is, that which was, and that which is yet to be - all this is nothing but this Infinite Being. Though He grows beyond His own nature into the form of the objective universe, He still remains the lord of immortality.(Svet Up 3.15)

Answer 2

Here I am giving a couple of examples -

The entire Isha Upanishad (one of the principal Upanishads) is actually the 40th chapter of Yajurveda Sanhita (Shukla Yajurveda).

Siva Sankalpa Upanishad (one of the minor Upanishads) is also part of the Yajurveda Sanhita [Shukla Yajurveda] (Chapter 34, hymns 1-6).
