(To be said whenever eating)
Rabbi Chaim Vital writes in Sha’arei Kedusha (gates of holiness) that his master, the Ari HaKadosh, told him to be very scrupulous when eating because one who wishes to become a Tzaddik needs to eat in a very exhalted manner.
There are many complex and mystical intentions with divine names when eating. It’s important to have least have the basicconsciousness to: separate the good from the bad (spiritually), elevate the fallen sparks, rectify the reincarnated souls (from the food), rectify the spiritual worlds and bring divine abundance to them.
This prayer serves to ask the Master of the Universe to assist one in this immensely holy work:
May it be your will, Lord my God and the God of my forefathers, that through the power of [the numerical values associated with the intentions] M’U (מ״ו 46), NA’CH (נ״ח 58), LECH’EM (לח״ם 78), DA’K (ד״ק 104), P’AD (פ״ד 84), that add up to 370 supreme lights that are two times אלף למד אלף למד spelled out [from the name אל] that my eating achieve the same effect as the sacrifices that united the upper forces from below to above so that the essence of the eating goes to the liver, and from the liver to the heart, and from the heart to the brain from below to above, from Assiyah to Yetzirah, from Yetzirah to Beriyah, and from Beriyah to Atzylut, level above level, until the Infinite Ein Sof, blessed be He, and, from there, great sustenance is brought down and flows to all the worlds until it reaches me and each and every one of my limbs should be strenghtened with its counterpart above.
And may it be your will, Lord my God and God of my forefathers, that all sparks of holiness from this food here, and all spirits reincarnated there, should be filtered and rectified properly, and whatever wasn’t filtered and rectified, You Almighty God, who performs kindness with your immense compassion, complete their filtering and rectification, and do it for the sake of your great name so that they shouldn’t sin or harm anymore, protect me and save me from all forbidden eating and ensure that no failing should come to me, and return them to the holy side as they were originally, clean of all evil, and may all our souls be cleansed.
“And God will be King over all Earth on that day when He will be One with His Name”

“May the pleasantness of the Lord our God be upon us and the fruits of our hands be established for us and in themselves”
