We do not speak of “Atzmut” (Essence of God) at all. This is because the root and the place of the creatures begin in the thought of creation. Ein Sof (the Infiniteness of God) pertains to the Thought of Creation, which is “His desire to do good to His creations.” This is considered Ein Sof, and it is the connection between the Essence of God and the souls. This is God’s “desire to give delight to the creatures.”
Ein Sof is the beginning. It is called “a Light without a vessel,” yet here is the root of the creatures, meaning the connection between the Creator and the creatures, called “His desire to do good to His creations.” This desire begins in the world of Ein Sof and extends through the world of Assiyah, which is our physical world. We can only relate to Ayn Sof as “the desire to enjoy”. Here is the beginning of the engagement with God at the highest levels. it is called “Light without a vessel.”
God’s desire is to do good to His creations.” This desire begins in the Highest worlds and extends through the lowest world. Souls can receive Lights according to what they have corrected and arranged. Thus, the souls can receive light, each according to its ability and nature. Thus there are all these attributes in different souls.
Ein Sof. is the root of the creatures, which wants to impart them delight and pleasure. It is called “His desire to do good to His creations.”
There is no change in Godliness. This is the meaning of “I the Lord do not change.” There are no Sefirot and aspects in Godliness. The will to receive defines the “creature” and a “new aspects” they may acquire. Change and growth begins from the place where the will to receive begins to receive “impressions”. One’s speech is aspects, parts of these impressions. Here with these “impressions” is begins a correlation between the Light and the will to receive.
This is called “Light and vessel.” , There is no utterance of action made by the Light of God without a vessel, since a Light that is not attained except in a vessel. Which is prompted by these “impressions” of desire which are Ayn Soff (Infiniteness of God). The Light that expands into our vessels, meaning into our will to receive is what we call Ein Sof. This is the connection of the Creator with the creatures, it being “His desire to do good to His creations.”
Our will to receive receives the expanding infinite Light, the expanding Light is then called Ein Sof. It comes to the receivers through many covering and vessels so that the beings below one will be able to receive it. All the varying aspects and the changes to the Light are made only according to the receiver. Their ability to receive the infinite light defines the nature of the light they receive. When we speak of different aspects of lights in the many worlds, these lights are in potential for revelation below. And when the receiver attains these aspects in this world here below, they are called “actual.”
Spiritual manifestation is when the “impression” of desire and the attained will come together, as without the “impression” of desire there is no way for the light to be attained, since there is no desire to obtain the aspect of the Light.
