The disciplinary observances which we chiefly remark in the _Rule_ are the raising up of the hands, the striking the breasts, and the genuflexions prescribed at the time of prayers and of the Holy Sacrifice; the perpetual psalmody: "To sing the three times fifty (Psalms) is an indispensable practice"; the purity of life required in the priest: "There shall be no permanent love in thy heart, but the love of God alone; for pure is the Body which thou receivest: purely must thou go to receive it" (strophe 65). The use of the sign of the Cross is mentioned at strophe eighty-eight; and at eighty-six we find mention of the canonical hours, and at eighty-nine of the ancient custom, still preserved in many parts of the Liturgy, of praying erect, of not kneeling on Sundays, and of genuflecting on entering the church or place where God's glory dwells. The practice of fasting, and of other corporal austerities, is also inculcated; and while in the 102nd and 106th strophes, Sundays and festivals are exempted from the law of fasting, the fast of Lent (strophes 105, 109, and following), of Advent (strophe 111), of two fasting days in each week, (strophe 110), and of the Quarter Tense (strophe 114), are specially mentioned. We also find an enumeration of the festivals as they are celebrated by the Church even at our day; the Sundays, festivals of the apostles, of noble martyrs, and of all the saints; the "night of great Christmas", the Epiphany, when the star led the wise men to Bethlehem; Easter; "the festivals of the King of Truth"; Pentecost; and even the festival of the birth of St. John the Baptist.
