A ritual used to bring divine light into the house, dwelling, or building so as to banish all darkness and introduce blessing and holiness through the use of a number of candles, at least one per room of the building.  First introduced in this 2018 post.

Supplies and tools needed for this ritual:

• One large white candle (a tall taper or glass-encased candle work perfectly)
• A bunch of small candles, one for each room in the house (tealights are most preferred, especially in their metal tins). These candles must all be the same color; white is always a good option, but they may be colored appropriately for a specific end of your choosing.
• Three small white candles
• Two small white dishes
• Holy oil
• A blessing oil of your choosing
• A long match or igniting stick
• Optionally, a crucifix or other symbol of Divinity
• Optionally, a wand

First, as much as is possible, ensure that the house is already physically clean before doing this work . Sweep, mop, vacuum, dust, take out the trash, do the dishes, do the laundry, beat the rugs, wipe the windows, and so forth, whatever you need to do to get the house physically clean.  Likewise, if at all possible, undertake a preliminary round of spiritually cleansing in the house as well: banish, light cleansing incense, use spiritual floor washes, sweep with a consecrated broom, and so forth, whatever you need to get the house spiritual cleansed.  The usual protocol is to perform such cleaning and cleansing from top-to-bottom, back-to-front, such that all the physical and spiritual filth is ultimately swept out the front door.  Having the house physically clean and spiritually cleansed before this ritual will allow the rest of this work to go much smoother and take effect more strongly and quickly in the home.  Similarly, be sure you’re clean and cleansed yourself before taking on this work.

On a large, clean working space, preferably in the kitchen or living room or other “center” of the house, arrange all the necessary supplies. Anoint the large white candle with holy oil and set it atop one of the white dishes, and all the other candles (saving the three white ones) around it with a blessing oil of your choosing; this can also be the same holy oil as you used on the large candle and is best for general blessings, but it can also be something more directed for a specific purpose (money-drawing, peace, reconciliation, joy, love, etc.).  Place the three extra white candles atop the other white dish in a triangle pattern, and set it aside for the time being, ideally covered with a white cloth or another white plate if one is available.  If so desired, take your chosen symbol of Divinity and set it up on the table or behind it where it can be seen during this work, preferably above or behind the main large candle.

Once all the candles (except the last three that were set aside) are anointed, light the large candle, and exorcise and consecrate it:

I conjure thee, thou creature of fire, by him who created all things both in heaven and earth, and in the sea, and in every other place whatever, that thou cast away every phantasm from thee, that no hurt whatsoever shall be done in any thing. Bless, oh Lord, this creature of fire +, and sanctify it that it may be blessed +, and that it may burn for your honor and glory +, so neither the enemy nor any false imagination may enter into it, through the Most High and Holy Creator of All. Amen.

Recite a preliminary prayer that allows you to set your mind to the work. For this and other general works, I use the following, which is based off the Preliminary Invocation from the Arbatel (aphorism II.14) and with an invocation from the Heptameron:

O God, mighty and merciful!
O God, great, excellent, and honored throughout endless ages!
O God, powerful, strong, and without beginning!
O God, wise, illustrious, just, and divinely loving!
O God, Lord of Heaven and Earth, maker and creator of all that is visible and invisible; I, though unworthy, call upon you and invoke you, through your only begotten son our Lord Jesus Christ, in order that you give your Holy Spirit to me, which may direct me in your truth, for the good of all. Amen.

I ask you, most holy Father, that I should fulfill and perfectly realize my petition, my work, my labor today. Grant to me your grace, that I may use these great gifts of yours only with humility, fear, and tremblings, through our Lord Jesus Christ with your Holy Spirit, You who live and reign, world without end. Amen.

Pray:

Grant, o Lord, that as I light this candle in your honor and glory, that your divine Light may fill up this home as light fills up the dawn to cast away the darkness of night. Bless this home with your grace, bless this home with your protection, bless this home with your presence that all darkness, all defilement, and all death may flee this place and that only joy, life, and light remain. May the seal of your holiness descend upon this house, and may all those who abide within it rest easy under your guidance. Amen.

After this, recite the Our Father, the Hail Mary, and the Glory Be over the candle.

From the large candle, light all of the smaller candles for each of the rooms of the house. If the large candle is a taper, use that candle to light all of the others; if you can’t do that, use a long match or other wooden stick that can hold a flame to transfer the flame from the large candle to the smaller ones. , As you do this, say a quick blessing upon the smaller candle as you light it that quickly and succinctly captures the intent for the blessing.  A non-exhaustive list of of such blessings can include the following, depending on your intent:

• “May the light of God fill this home.”
• “Fill this home with peace.”
• “Grant prosperity upon this home.”
• “Heal those who abide in this home.”
• “Protect the body and soul of all those who live here.”
• &c.

This next step is optional, but highly recommended.  Once all the candles are lit, using your dominant hand’s index finger (or a wand, if one is available, or whatever is left of the long match/igniting stick used), energetically link the flame of the large candle to each of the smaller candles.  This may be done by energetically “tapping into” the flame of the large candle and forging an energetic channel to the flame of the smaller candle, then back to the large candle; perform this process again, starting from the flame of the small candle to that of the large candle and back.  Do this for each of the smaller candles that have been lit.  Once all the smaller candles are energetically linked to the main candle, channel or invoke the light of the Divine into the large candle to set and fix the connection. Even though a strong connection was already formed between the large candle and the smaller candles by spreading the flame out, it is recommended to reinforce that connection energetically as well; those who use crystal grids will be familiar with this or similar techniques.

At this point, pray over all the lit candles for your intent for the blessing upon the house over the main candle. This part is really up to you, so long as you pray from the heart about it. You can use any number of psalms, invocations, litanies, or other prayers for this purpose, so long as it supports what you’re trying to do.  For instance, you might use Psalm 122 if you’re blessing the house for prosperity, or Psalm 29 to purify the home generally, and so forth.  Take as long or as short as you need; use whatever resources you feel moved to use. Essentially, pray that as each of these candles shines their light into each room of the house, that God may shine Light throughout the entire home, that all those who abide, live, reside, visit, or are invited in may dwell in his Light, and that you may obtain the blessing of his grace for what you seek in the home.

Take all the candles one by one and set them in each room of the house.  The most essential places are where you spend most of your time, but it really is best to put one in every room: bedrooms, bathrooms, closets, garage, basement, hallways, crawlspaces, attic, everywhere. The idea is that, no matter where you are in the home, you can see at least one candle burning; if you need to use more than one candle in a room to achieve this effect, do so.  Any shelves, wall sconces, or hanging candleholders or candelabras can be put to good use for this purpose. Just take care that the candleflame doesn’t go out in the process of moving and establishing that candle from the large candle to wherever it needs to go, and be careful of where you put each candle that it doesn’t cause a fire hazard.  If one’s spirits, saints, angels, or gods agree to it, set candles in already-existing shrines around the house where you may have them to further empower the work at hand—just check with them before you do so, as such a divine energy may not always be compatible for all shrines or altars.  Work around the house from the inside outward from where you started, so that the Light “spreads” throughout the home.

Once the candles have been set throughout the entire house, return to the large candle. If, in the course of setting lights throughout the house, you noticed that there’s a particularly strong “heart center” of the house, take this large candle and your chosen symbol of Divinity (if you have/want one) and reestablish it there.  Otherwise, leave the large candle and the symbol of Divinity where it was where it can burn out completely, such as on the kitchen table, empty counter, fireplace mantel, or living room coffee table.  While the large candle is burning, throughout the house generally but especially in the light of this candle, avoid engaging in any arguments, heated words, violence, blasphemy, or other actions that run counter to the presence and blessing of God.

At this point, take the plate with the three white candles on it, uncover it if it was previously covered, and set it in front of the main candle and the symbol of divinity. For the final part of this ritual as an act of thanksgiving, leave these candles unanointed, but set them up in a triangle pointing upwards on the dish pointing towards the main candle and symbol of divinity.  Light the candles one by one, and recite Jonah 2:9 once for each candle:

But I will sacrifice unto thee with the voice of thanksgiving;
I will pay that that I have vowed.
Salvation is of the Lord.

Follow this up with any other silent prayers of thanksgiving, gratitude, respect, and honor to God. Once done, go about your business. Let all the smaller candles (including the thanksgiving ones) burn out on their own before collecting any tins or residue from around the house. The larger candle should be left to burn out on its own as well; if this is a multi-day candle, such as a novena candle, pray over it at sunrise and sunset for as long as it burns to continue the blessing of God into the home.  Once this candle is burnt out, dispose of it as well. Enjoy your happily blessed home.
