Holy Zohar text. Daily Zohar -286.

Tikkun 21 – 27

The prayers are considered as sacrifices, which in Hebrew is called in two names, קרבן and עולה, literal meaning , closeness and elevation.
The words of the prayer elevate Malchut in the aspect of the name ADNY אדני to the name YHVH יהוה. This creates the unification of the two names as יאהדונהי and allows flow of the light to Malchut.

In Song of Songs 8:5 we read “מִי זֹאת, עֹלָה מִן-הַמִּדְבָּר,” “Who is this that come up from the wilderness, leaning upon her beloved? Under the apple-tree I awakened thee…”. The word wilderness has the same letters as מדבר, meaning the one that speaks. The praise here is for the prayer that ascends and makes a unification, to bring birth to a new light.
The words we use in our prayers are very important to create the channel to the higher levels.

The Hebrew words created the world and built the paths between the Sefirot. To climb up we need to use the letters.
If you do not read Hebrew, then scan the sacred text to make it a vehicle for your prayer. The eyes are at the level of Chokmah and with the words and consciousness we create the necessary force to elevate our prayers.
