Neshome נשמה

(7) the LORD God formed man from the dust of the earth. He blew into his nostrils the breath of life, (nishmat chayim) and man became a living being.

ויפח באפיו AND BREATHED INTO HIS NOSTRILS — He made him of both, of earthly and of heavenly matter: the body of the earthly, and the soul of the heavenly (v'neshamah min ha'elyonim). For on the first day were created heaven and earth, on the second, He created the firmament for the heavenly beings, on the third He said, “Let the dry land appear” — for the earthly beings, on the fourth He created the lights for the heavenly beings, on the fifth He said, “Let the waters swarm…” — for the earthly beings. Consequently on the sixth there had to be created a being composed of both, of heavenly and of earthly matter, for otherwise there would have been envy (lack of harmony) among the works of Creation, in that there would have been devoted to one class of them one day more of the Creation than to the others (Genesis Rabbah 12:8).

When one awakens, he recites:
My God, the soul You have placed within me is pure (elohai neshamah shenatatah bi tehorah).
You formed it within me,
You breathed it into me,
and You guard it while it is within me.
One day You will take it from me and restore it within me in the time to come.
As long as the soul is within me (kol zman shehanshamah b'kirbi), I thank You,
O Lord my God and God of my ancestors, Master of all worlds, Lord of all souls (adon kol hanshamot).
Blessed are You, O Lord, who restores souls to lifeless bodies (baruch atah hashem hamchazir neshamot lifgerim metim).

Just as the Holy One, Blessed be He, fills the entire world, so too the soul fills the entire body (af neshamah maley et kol hagoof.)
Just as the Holy One, Blessed be He, sees but is not seen, so too does the soul see, but is not seen (af neshamah roeh v'eynah nireyt).
Just as the Holy One, Blessed be He, sustains the entire world, so too the soul sustains the entire body (af neshamah zanah et kol hagoof).
Just as the Holy One, Blessed be He, is pure, so too is the soul pure (af neshamah tehorah).
Just as the Holy One, Blessed be He, resides in a chamber within a chamber, in His inner sanctum, so too the soul resides in a chamber within a chamber (af neshamah yoshevet b'chadrey chedarim), in the innermost recesses of the body.
Therefore, that which has these five characteristics, the soul, should come and praise He Who has these five characteristics.

The lifebreath of man is the lamp of the LORD Revealing all his inmost parts (ner hashem nishmat adam chofesh kol-chedrei-veten).

... Just as bedikat chametz (checking for chametz) is not valid by sunlight, nor by moonlight, nor by the light of a torch, but only by the light of a candle, so too the bedikah (checking) of the yetzer hara must be by the light of the soul (l'or hanshamah) which is called 'ner' (candle), this is what is written (proverbs 20:27) "the candle of Hashem is the soul of man (ner hashem nishmat adam), which searches the chambers of one's inner being.

As Rabbi Shimon ben Lakish said: The Holy One, Blessed be He, gives a person an additional soul (neshamah yeterah) on Shabbat eve, and at the conclusion of Shabbat removes it from him, as it is stated: “He ceased from work and was refreshed [vayinafash]” (Exodus 31:17). Rabbi Shimon ben Lakish expounds the verse as follows: Since he ceased from work, and now Shabbat has concluded and his additional soul is removed from him, woe [vai] for the additional soul [nefesh] that is lost.

Let all that breathes praise the LORD. Hallelujah.

(kol hanshamah t'hallel yahh halelu-yahh)

On a related topic, the Gemara cites that Rav Yehuda said: One who goes out during Nisan and sees trees that are blossoming recites: Blessed…who has withheld nothing from His world, and has created in it beautiful creatures and trees for human beings to enjoy. Rav Zutra bar Toviya said that Rav said: From where is it derived that one recites a blessing over scent? As it is stated: “Let every soul praise the Lord (kol hanshamah t'hallel yahh)” (Psalms 150:6). He explains the verse: What is it from which the soul derives benefit (shehanshamah nehenit) and the body does not derive benefit from it? You must say: That is scent. Even over items from which only the soul derives benefit, one must recite a blessing and praise God.

The Topheth has long been ready for him; He too is destined for Melech— His firepit has been made both wide and deep, With plenty of fire and firewood, And with the breath of the LORD (nishmat hashem) Burning in it like a stream of sulfur.

By the breath of God ice is formed, And the expanse of water becomes solid.

(minishmat-el yitten-qarach v'rochav mayim b'mutzaq)

The spirit of God formed me; The breath of Shaddai sustains me.

(ruach-el asatni v'nishmat shaddai t'chayeni)
