This shows Mary's assumption into heaven with her body and soul. This painting is attributed to Bartolome Murillo.
Solemnity of the Feast of the Blessed Virgin Mary Into Heaven Bodily and Soul is celebrated by the Catholics from all over the globe in a grand mass and procession. According to Roman Catholic doctrine and the traditions of the Catholic Church, the Blessed Virgin Mary (Mary, the mother of Jesus) "having completed the course of her earthly life, was assumed body and soul into heavenly glory."[1] This means that Mary was transported into Heaven with her body and soul united. The feast day recognizing Mary's passage into Heaven is celebrated as The Feast of the Assumption of the Blessed Virgin Mary by Roman Catholics. This doctrine was dogmatically and infallibly defined by Pope Pius XII on 1 November 1950 in his Apostolic Constitution Munificentissimus Deus. In those denominations that observe it, the Feast of the Assumption is commonly celebrated on August 15.
Possibly the most famous rendition of the subject in Western art, Titian's Assunta (1516-18).
The Virgin Mary's heavenly birthday
The Assumption is important to many Catholics as the Virgin Mary's heavenly birthday (the day that Mary was received into Heaven). Her acceptance into the glory of Heaven is seen by them as the symbol of the promise made by Jesus to all enduring Christians that they too will be received into paradise. The Assumption of Mary is symbolised in the Fleur-de-lys Madonna.
he Feast of the Assumption is a Public Holiday in many countries, including Austria, Belgium, Cameroon, France, Italy, Lebanon, Luxembourg, Paraguay, Malta, Poland, Portugal, and Spain. In Guatemala it is observed in Guatemala City and in the town of Santa Maria Nebaj, both of which claim her as their patron saint. Also, this is the celebration of Mother's Day in Costa Rica. In many places, religious parades, and popular festivals are held to celebrate this day. In Anglicanism and Lutheranism, the feast is kept, but without official use of the word 'Assumption'. Her feast day is Fête Nationale of the Acadians, of whom she is the patron saint. Businesses close on that day in heavily francophone parts of New Brunswick, Canada. The Virgin Assumed in Heaven is also patroness of the Maltese Islands and Her feast, celebrated on the 15 August, apart from being a public holiday in Malta is also celebrated with great solemnity in all the local churches.

The Assumption in Catholic teaching
In Ludwig Ott's Fundamentals of Catholic Dogma he states that "the fact of her death is almost generally accepted by the Fathers and Theologians, and is expressly affirmed in the Liturgy of the Church," to which he adduces a number of helpful citations, and concludes that "for Mary, death, in consequence of her freedom from original sin and from personal sin, was not a consequence of punishment of sin. However, it seems fitting that Mary's body, which was by nature mortal, should be, in conformity with that of her Divine Son, subject to the general law of death".[3] The point of her bodily death has not been infallibly defined, and many believe that she did not die at all, but was assumed directly into Heaven. Indeed, the papal decree which infallibly proclaims the doctrine of the Assumption, the Apostolic Constitution Munificentissimus Deus, leaves open the question whether, in connection with her departure, Mary underwent bodily death; that is, it does not dogmatically define the point one way or the other, as shown by the words "having completed the course of her earthly life".
