He showed me [His Mother's] ascend to heaven, the happiness and solemnity with which she was received, and the place where she is...The glory my spirit experienced in seeing so much glory was magnificent. The effects of this favour were great. (St Teresa of Avila, 'Collected Works' 1:353)
That is true life...
Death, be not aloof,
In dying first, may life be,
I die because I do not die
(St Teresa of Avila "Collected Works" 3: 376)
she only went through the tomb but did not delay there; her tomb became the shrine of her glorious Assumption into Heaven. That Mary, at the end of her earthly existence was assumed into heaven was defined as an article of faith on November 1, 1950. Jerusalem Catholics celebrated the definition by a great procession...A first Church was erected by the patriarch Modestus but it was again destroyed, except the little edicule over the Tomb, before the arrival of the Crusaders, who rebuilt it, keeping the form of a lower and upper Church.
The ruin of the sacred monument would nevertheless have been inevitable, had not the Franciscans entered into possession of the Church in the second half of the 14th century and carried out important restorations. For two centuries the Franciscans had the exclusive and peaceful possession of the Tomb, while the Armenians, the Greeks, the Abyssinians and the Syrians carried out their liturgy on altars within the crypt. With the coming of the Turks, in 1517, began the intrigues of the Greeks and finally in 1757 the Franciscans lost the place completely. This usurpation has never been made good, and today the Church is shared by the Greeks and the Armenians, while the Syrians and the Copts are allowed to celebrate the liturgy within the shrine. The building today is very badly kept, but beneath all the filth one can recognize its one time beauty in the Crusader and Byzantine structures. The church was completely flooded in 1948 and 1955, and it unexpectedly helped to clean it.
How could she became the prey of the ravages of death. How could decomposition claim possession of the body in which the life of Our lord was conceived" (Second Seromn of Assumption)."
