In the paths of kabbalah one encounters archetypal crisis situations.Times in one's life where one is facing true difficulty and suffering.Tragedy,loss,misfortune,violent upheaval,this is often called the long dark night of the soul.But these preordained crisis points lead to transformation and change.While they are usually devastating,this clears the old personal structures,to make way for the new.To lose all and find the new.I hope this helps......

The Veil
Different kabbalists place the Veil on different places, sometimes underneath Tiphereth, sometimes just above or below Yesod. They don't seem to know just where to put it. What actually is the meaning of those two terms? They are boundaries. A veil or curtain is often used in initiations. Once one has passed the veil or curtain one has stepped into another, hidden world. Like the Veil behind the High priestess in the Tarot. The Abyss has the same meaning. Crossing the Abyss means that one has stepped into another realm. A veil or curtain is made out of cloth, and cloth is the most natural, man-made thing used to cover things up. The genitals (Yesod) is the first area of the body that is covered up with a piece of cloth.

It is my opinion that the Veil on the Tree of Life is situated at the boundary of the world of Assiah and the world of Yetzirah. That is in complete accordance with the traditional meaning of initiating a novice. One leaves the mundane world aside and steps for the first time into the inner realms of the human psyche which lie just beyond the physical. It is called the Veil because a veil covers up something. Lifting a veil or a curtain is like stepping in another room.
The Abyss
The Abyss traditionally is situated underneath Chochmah and Binah, and it is said that Daath lies across it. This corresponds with the boundary of the world of Briah and the world of Atziluth. This boundary is called the Abyss because the transformation that happens here when ascending the Tree is like stepping into an abyss, into a void, into an emptiness of the mind. The exact same terms are used in Buddhism to describe the experience of discovering the divine and true essence of man. This is a real experience, not an abstract concept.
The Wall
There should be a third boundary between the world of Briah and the world of Yetzirah, which runs through Tiphereth.

I call it the Wall, because here the transformation of the ego happens. Building an ego is like building a stone tower. Living in this self-enclosed tower, it is a wall that separates one from the outer world, that is of feeling one with the rest of creation. It is in our language when we speak of somebody who has built a wall around himself, of breaking down walls between people. The Berlin wall was built to divide people, it was broken down to unite people. Becoming selfless, or sacrificing the ego when ascending the Tree is like breaking down a hard wall, as the ego is tough to dissolve.
