This work begins: "In order rightly to understand the nature of a virtue, the duties which it imposes, the acts which it ought to inspire, and the spirit in which they ought to be accomplished, it is necessary to understand as clearly as possible its object and its end. What, then, is the object, what is the aim of the adoration of the Most Blessed Sacrament, the most excellent act of all the virtue of religion? This is what we desire to point out in a simple and practical manner for the greatest utility of all those souls who, by the influence of God's grace, have enrolled themselves in our various eucharistic associations, where the adoration of the Most Holy Sacrament is the principal object. The spiritual link which unites in one sole family of adorers the members of the Society of Priest Adorers and those of the Monthly Adoration in the parishes, together with the religious of the Congregation of the Most Holy Sacrament, allows them to be addressed with the same instructions which Pere Eymard gave to his sons in his rule, and which are the most perfect expression of his thought and mind. It is, in fact, the same sap which nourishes the religious trunk and the secular branches of the eucharistic tree planted by the venerable founder in order to produce the fruits of love, of honor, of satisfaction, and glory which the divine King of the sacrament desires so greatly and so legitimately to enjoy. The adoration has a threefold object, and ought to be considered in a threefold relation. It is first Our Lord Jesus Christ that it ought to honor beneath the eucharistic veils; next it is the love of the adorer which it ought to sanctify; and, lastly, it is our neighbor which it ought to assist and to help, and especially the Church." This work continues to give a beautiful exposition of the most Holy Eucharist and devotion to It
