It is part of how a guru works. They create a bubble that allows us to expand quickly and without overloading our system. The sending of Light helps to tune our system, provide knowledge and increase our progress.
It is not a one time thing for best results.

Communion - A Mystical Perspective...
Posted 22 May 2014 - 08:37 AM
26 While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, “Take and eat; this is my body.” 27 Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28 This is my blood of the[a] covenant, which is poured out for many for the forgiveness of sins. 29 I tell you, I will not drink from this fruit of the vine from now on until that day when I drink it new with you in my Father’s kingdom.” 30 When they had sung a hymn, they went out to the Mount of Olives.
The words are describing in symbolic terms the meaning of true communion. Jesus is describing an advanced form of light transmission (or shared oneness/presence), similar to guru/divinity yoga. Historically, there have been two main different types of transmission. First, earth or Mother energy often called Shakipat (leading to Kundalini). And second, sharing of presence (or knowledge) which momentarily create a state of "clarity of mind".
In communion, the "body" represent body/mother energy or "Kundalini". The "blood" represents spirit energy or "state of knowledge". In Christian terms, the state of knowledge is often also called "the peace that passes all human understanding". Bringing together both components greatly accelerates overall human development because you have the "kundalini" force pushing ongoing "clarity" rapidly forward, while the guru/master provides an ongoing "sharing" of peace (mental clarity) to help protect from the normal issues that can come from kundalini. This shared clarity or peace is also why many Christian's will describe a "top down" rather than a "bottom up" feeling to energy/kundalini.
In more esoteric gnostic christian texts, it is often call things like the "bridal or marriage chamber". As in the Gospel of Thomas...
75. Jesus said, "There are many standing at the door, but those who are alone will enter the bridal suite."
Also, from the Secret Gospel of Mary...
12. Disciples of Mary said to her, “We are going on a pilgrimage to the holy land so we might see where you and the Lord lived.” Mary said to them, “The holy land is wherever a child of Light goes, and it is where the child of Light abides. The holy land is where the Anointed and the soul are joined, it is the bridal chamber.”
23. Mary spoke, and said, “There is baptism, chrism and wedding feast, and there is the ransom and bridal chamber. Baptism is water, chrism is fire and the ransom is earth. The wedding feast is the air, for in the Spirit we shall meet the Anointed on the Day of Joy, and then the element of the bridal chamber shall be fully revealed. Everything the Lord accomplished he accomplished in a mystery, and the Anointed Bride is the mystery.”
48. Mary taught her disciples, saying, “The Aeons of Light are the handmaids of the Bride at the wedding feast, and the best man is the Son of Adam at the wedding; in the bridal chamber the soul acquires intimate acquaintance with the Anointed and becomes the Anointed. Until that time, sing and dance and rejoice, for it is to those who abide in joy that the Shekinah comes, and it is through her that you will enter the bridal chamber.”
Best wishes.
