The Grail Message is a Work entitled: In The Light of Truth brought to mankind by Abd-ru-shin whose civil name was Oskar Ernst Bernhardt. He was born in Germany in 1875 and dies in 1941. The Work In The Light of Truth, The Grail Message is a series of 168 lectures, in three volumes, that explains Creation and the Creator.

The Work is a map of the whole of Creation, from the highest heights in Paradise to the deepest depths in Hell. It shows how Creation came into being and what is man's place in it. It shows and details the reason why man is on earth, his mission and how he should accomplish it. The Grail Message is a completion of the Work of Jesus Christ, the Son of God.

The Grail Message is addressed to each individual human spirit who has a genuine longing for the Truth which will bring him spiritual freedom and true peace. In the Work In The Light of Truth itself will be found the explanations of the word "Grail".

The Message does not bring a new religion, but is intended as the torch to help all serious listeners or readers find the right path, which leads them to the longed-for height (Paradise).
