פתח את יודך ומשביע לכל חי רצון, “Open your hands and bring beneficent to all living desire”. The Holy Ari explains about verse from Psalms that when you change the “Nikud” (Vowels) on the word hands it reveals the word “your Yods י”.
The letter sequence that represent connection of the Light of the Creator between upper and lower, judgment אדני and Mercy יהוה, forms יאהדונהי.
When we open the sequence and take the two י, we have numerical value of twenty same as the small Gematria of פתח and that connects us to the Light of Keter of Chokmah. The middle six letters, אהדונה, are according to the Ari connect to Yesod, which is the gate and channel of Light to Malchut.
The sequence יאהדונהי, is known as the Amen sequence, that by mating together the revealed force of this world of judgment with the supernal name that represent mercy, the Light flows down. We are not allowed to pronounce this name, just scan it with our eyes.
To add the aspect of Mercy in a person’s life he can merge the higher name יהוה with his name.
For example for the name שמעון the combination will be ישהמועהון. For the name שרה will be ישהרוהה.
Meditating on this combination will inject mercy into the name and soul of the person.
