Experience teaches us that plants and fruits do not attain maturity until they have produced their seeds, which are necessary for the reproduction of their species. In the same way our virtues will never be sufficiently perfected, or reach their maturity, until they produce within us an ardent desire to make further progress. This desire is the spiritual seed which produces new degrees of virtue. SPIRITUAL FLOWERS. Mary is a most beautiful rose, which dared not open its petals even to the gentle breeze of an Angel!--_St. Ambrose._ How precious and how delicate a flower is purity! A sigh, a look, a word is enough to wither it! On this account chaste souls continually distrust themselves, and flee from the slightest occasions of danger.--_Nouet._ The rose is the symbol of love and charity; its petals are red, and formed like a heart. Such should be the actions of the spouses of Jesus Christ. They should have as many hearts as they have petals-- that is to say, hearts full of love, and like petals in the little esteem they should have of their actions.--_St. Francis of Sales._ EXAMPLE. _Consecration of the Saturday to Mary._ Holy Church is ever desirous to maintain a tender devotion in the hearts of the faithful towards the Most Blessed Virgin, and from the earliest ages of Christianity she has encouraged the consecration of the Saturday to her. It is related that there was in the church of Santa Sofia at Constantinople a picture of the Mother of God which was veiled during the rest of the week, but on Friday evening the veil was raised without human aid, and lowered on the evening of Saturday. Thus did Almighty God manifest His Will that _Saturday_ should be dedicated to Mary. It was on Saturday she took so great a part in the work of our redemption, and it was fitting that on the morrow of the day when she so bitterly wept over the sorrowful scene of Calvary we should remember her tears shed for us in a special manner. Again, on Saturday God rested from His work in the creation of the world, and the Church consecrates this day to her, to honour the mysterious repose of the Holy Ghost in her Immaculate Heart, and that of Our Blessed Saviour in her chaste womb. Saturday is the introduction to Sunday--the symbol of eternal rest--and the Holy Virgin is truly invoked under the title of 'Gate of Heaven'--_Janua Coeli_. Saturday, moreover, is the day between Friday, the day of mourning, and Sunday, the day of joy--and the Holy Virgin is the mediatrix between God, Who is Eternal Beatitude, and man, who is subject to endless evils and miseries. Mary is the way to arrive at Jesus, and Saturday is a prelude to the solemnity of Sunday. Saturday is as a magnificent portal consecrated to the Mother of God, by which we enter the Sanctuary of God Himself. The Saints held this day in great esteem--on it they redoubled their pious exercises--and many begged, as a signal favour, that they might die on a Saturday.
