When Jozef Rulof was born in 1898 in the rural area of 's-Heerenberg in the Netherlands, his spirit guide, Alcar, already had big plans for him. Alcar had passed into the afterlife in 1641, after his last life on earth as Anthony van Dijck. Since then, he had accumulated vast knowledge about human life on earth and in the afterlife. To bring this knowledge down to earth, he wanted to turn Jozef into a writing medium.

After Jozef established himself as a taxi driver in The Hague in 1922, Alcar first turned him into a healing and painting medium, in order to create the trance necessary to receive books. Jozef received hundreds of paintings, and thanks to his sales he was able to keep the publication of the books under his control.

When Alcar began transmitting his first book "A Vision of the Beyond" in 1933, he gave Jozef the possibility to choose the depth of the mediumistic trance. He could put Jozef into a very deep sleep and take over his body to write books outside the medium's consciousness. Then Alcar could use his own choice of words from the first sentence to explain to the reader from that moment on how he himself had come to know the reality on the level of the soul, in which the eternal life of the human soul is central.

Another possibility was to apply a lighter trance, in which the medium could feel what was written during the writing. This would allow Jozef to grow spiritually with the knowledge transmitted. However, then the accumulation of knowledge in the series of books would have to be in tune with the spiritual development of the medium. And then Alcar would only be able to give the explanations on the soul level if the medium was also prepared for it.

Jozef opted for the lighter trance. As a result, Alcar was somewhat limited in the words he could use in the first books. He let Jozef experience this by writing the word "Jozef" in trance. At that very moment, Jozef awoke from the trance, because he felt his name being called. To avoid this, Alcar chose the name André to describe Jozef's experiences in the books. Alcar also changed or avoided other names and circumstances in "A Vision of the Beyond", so that Jozef could remain in trance. Thus, the reader learns in this first book that André got married, but not that this happened in 1923 and that his wife's name was Anna.

In order to remain in harmony with Jozef's life of feeling, Alcar first allowed his medium to experience for himself what was described in the books. To do this, Alcar allowed him to leave his body, so that Jozef could perceive for himself the spiritual worlds beyond. The books describe their joint journeys through the dark spheres and the spheres of light. Jozef saw that, after his transition on Earth, the human being ends up in the sphere to which his life of feeling belongs.

In an out-of-body state, he also witnessed many transitions on Earth. The books describe what exactly happens to the human soul after cremation, burial, embalming, euthanasia, suicide and organ transplantation.

Jozef knows his past lives

The name André was chosen by Alcar, because Jozef had borne that name in a past life in France. André was an academic at the time, and the commitment to research everything in depth could help to go step by step deeper into the level of explanation of the books.

For example, in 1938 Jozef was able to receive the book "The Cycle of the Soul" from master Zelanus, a pupil of Alcar. In this book, Zelanus described his past lives. In this way, he showed how all the experiences of his past lives had ended up building up his life of feelings, and ensured that he could feel more and more.

By 1940, Jozef had developed enough to experience the book "Between Life and Death". As a result, he came to know Dectar, his own past life as a temple priest in Ancient Egypt. Dectar had increased his spiritual powers in the temples to a high level, thanks to which he could have intense out-of-body experiences, and also did not neglect his earthly life. These powers were now necessary to reach the ultimate degree of mediumship: cosmic consciousness.

Our cosmic soul

In 1944, Jozef Rulof was so developed as "André-Dectar" that he could experience spiritual journeys through the cosmos together with Alcar and Zelanus. Through the descriptions of these journeys in the book series "The Cosmology of Jozef Rulof", the highest knowledge of the beyond was brought to earth.

Now the masters Alcar and Zelanus could finally describe reality as they themselves had come to know it as truth. Only now could they use words and terms that describe the core of our soul and thus reveal the essence of the human being.

In cosmology the masters explain on the level of the soul where we come from and how our cosmic evolution began because our soul split from the All-Soul. André-Dectar now learned about his past lives on other planets and the gigantic developmental path his soul has travelled to evolve from a rarefied cell on the first planet in the universe to life on Earth.

In addition, with the masters he visited the higher cosmic degrees of life that await us after our earthly lives. Cosmology describes where we are going, and how our lives on earth are necessary for this. It sheds a cosmic light on the meaning of our life and the essence of the human being as a soul.

Christ University

The teachers were able to go through all the cosmic grades and transmit this ultimate knowledge because they themselves were aided by their order of teachers. This order is called the "University of Christ", because Christ is the mentor of this university.

In His life on earth, Christ could not pass on this knowledge because humanity was not ready for it. Christ was already killed for what little he could say. He knew, however, that His order would bring this knowledge to earth as soon as a medium could be born who would no longer be killed for this very thing.

That medium was Jozef Rulof, and the books he received heralded a new era: "The Age of Christ". Christ himself should have confined himself to the core of his message: selfless love. In the Christ Age, through Jozef Rulof his students were able to give a detailed explanation of how we rise in feeling by giving universal love and as a result reach higher spheres of light and cosmic degrees of life.

At the request of his teachers, in 1946 Jozef set up the Society of the Age of Christ to manage the books and paintings. In the same year he travelled to America in order to spread the knowledge he had received there, in collaboration with his émigré brothers. As in the Netherlands, he held trance lectures and painting demonstrations there.

Back in Holland, in addition to hundreds of trance lectures, he also held contact evenings for years, to answer questions from readers of the books. In 1950, Master Zelanus was able to write Jozef's biography "Jeus of Mother Crisje" with the name "Jozef" and the childhood name "Jeus", without breaking the trance.

The teachers knew that humanity would still not accept the University of Christ, in spite of all the knowledge and efforts transmitted by Joseph. Science will only accept a proof of life after death if it is achieved without a human medium, so that the influence of the medium's personality can be excluded.

That proof will be provided by what the masters call the "direct voice instrument". They predict that this technical instrument will bring direct communication between the human being on earth and the masters of light. At that time, Jozef and other masters will be able to address the world from beyond, and will be able to give humanity the happiness of the certain knowledge that we live infinitely as one cosmic soul.

Jozef passed into the beyond in 1952. At the end of his book "Spiritual Gifts", Master Zelanus had already mentioned that, after Jozef's transition, Jozef and the masters will no longer address human mediums, because the ultimate knowledge of the beyond can already be found in the books that Jozef was able to receive during his earthly life.
