(On Saturday nights, we light the Havdalah candle and say:)

בְּרוּכָה אַתְּ שְׁכִינָה, רוּחַ הָעוֹלָם, בּוֹרֵאת מְאוֹרֵי הָאֵשׁ.

(Fem:) Brucha at Shechinah, ru’ach ha-olam, boreyt me’orey ha-eysh.

בָּרוּךְ אַתָּה יי, אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, בּוֹרֵא מְאוֹרֵי הָאֵשׁ

(Masc:) Baruch atah Adonai, eloheynu melech ha-olam, borey me’orey ha-eysh.

Blessed are You, who creates the fire’s light.

,בְּרוּכָה אַתְּ שְׁכִינָה, רוּחַ הָעוֹלָם, הַמַּבְדִילָה בֵּין קוֹדֶשׁ לְחוֹל
.בֵּין אוֹר לְחוֹשֶׁךְ, בֵּין יוֹם הַשְׁבִיעִי לְשֵׁשֶׁת יְמֵי הַמַעֲשֶׂה
.בְּרוּכָה אַתְּ שְׁכִינָה, הַמַּבְדִילָה בֵּין קֹדֶשׁ לְקֹדֶשׁ

(Fem:) Brucha at Shechinah, ru’ach ha-olam, ha-mavdilah beyn kodesh le-chol, 
beyn or le-choshech, beyn yom ha-shvee’ee le-sheshet yamim ha-ma’aseh. 
Brucha at Shechinah, ha-mavdilah beyn kodesh le-kodesh.

,בָּרוּךְ אַתָּה יי, אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, הַמַבְדִיל בֵּין קֹדֶשׁ לְחוֹל
.בֵּין אוֹר לְחוֹשֶׁךְ, בֵּין יוֹם הַשְׁבִיעִי לְשֵׁשֶׁת יְמֵי הַמַעֲשֶׂה
.בָּרוּךְ אַתָּה יי, הַמַבְדִיל בֵּין קֹדֶשׁ לְקֹדֶשׁ

(Masc:) Baruch atah Adonai, eloheynu melech ha-olam, ha-mavdil beyn kodesh le-chol,
beyn or le-choshech, eyn yom ha-shvee’ee le-sheshet yamim ha-ma’aseh.
Baruch atah Adonai ha-mavdil beyn kodesh le-kodesh.

Blessed are You, who distinguishes between holy and mundane, 
between light and darkness, between Shabbat and weekdays. 
Blessed are You, who distinguishes between holy and holy.

Why is this havdalah different from all other havdalah ceremonies? On all other Saturday nights, we smell fragrant spices and we bless Hashem for distinguishing between holy and mundane, not holy and holy!
The reason we smell spices during havdalah in the first place has to do with the idea that on Shabbat each of us is given a neshama yetera, an additional soul. When the extra soul departs, our everyday souls mourn their companions’ loss. We must revive them with strong smells, like waking someone up with smelling salts. This isn’t necessary tonight because we are not leaving sacred time. 
Havdalah is a bittersweet ritual that marks the beginning of a new week and the end of Shabbat. Normally, when Shabbat ends we find ourselves in ordinary time, no more spiritually significant than any other weekday. Tonight, as we leave Shabbat we immediately enter another sacred time, Pesach. Therefore it would be inappropriate to bless Hashem for distinguishing between holy and mundane, as the Pesach seder is anything but an ordinary meal.
What does it mean, though, to distinguish between holy and holy? The simple answer is that Shabbat and Pesach are considered to be different ‘levels’ of holy. In fact, Jews believe the most sacred day of the year comes once a week. Even the highest of holidays, Yom Kippur, is a distant second. But here’s a better way of thinking about this difference in holiness: Jewish holidays are all sacred glimpses of our people’s past, but Shabbat is a rare vision of our future, a taste of the world to come. Both our history and our destiny are sacred, but only one of them is ours to choose.
