The following comes from Decisions for Successful Living written by Harold B. Lee, one of the Prophets of The Church of Jesus Christ of Latter-day Saints.
Turning from the love of the world to the Love of God.
1. Blessed Are the Poor in Spirit
"To be poor in spirit is to feel yourselves as the spiritually needy, ever dependent upon the Lord for your clothes, and your food and the air you breathe, your health, your life; realizing that no day should pass without fervent prayer of thanksgiving, for guidance and forgiveness and strength sufficient for each day's need."
2. Blessed Are They That Mourn
"To mourn, as the Master's lesson here would teach, one must show that 'godly sorrow that worketh repentance' and wins for the penitent a forgiveness of sins and forbids a return to the deeds of which he mourns."
3. Blessed Are the Meek
"A meek man is defined as one who is not easily provoked or irritated and forbearing under injury or annoyance. Meekness is not synonymous with weakness. The meek man is the strong, the mighty, the man of complete self-mastery. He is the one who has the courage of his moral convictions, despite the pressure of the gang or the club."
4. Blessed Are They That Hunger and Thirst After Righteousness
"Did you ever hunger for food or thirst for water when just a crust of stale bread or a sip of tepid water to ease the pangs that distressed you seem to be the most prized of all possessions? If you have so hungered then you may begin to understand how the Master meant we should hunger and thirst after righteousness. It's that hungering and thirsting that leads those away from home to seek fellowship with saints in sacrament services and that induces worship on the Lord's Day wherever we are. It is that which prompts fervent prayer and leads our feet to holy temples and bids us be reverent therein."
Learning to love our fellowmen
5. Blessed are the Pure in Heart
"If you would see God, you must be pure. There is in Jewish writings the story of a man who saw an object in the distance, an object that he thought was a beast. As it drew nearer he could perceive it was a man and as it came still closer he saw it was his friend. You can see only that which you have eyes to see. Some of the associates of Jesus saw him only as a son of Joseph the carpenter. Others thought him to be a wine-bibber or a drunkard because of his words. Still others thought he was possessed of devils. Only the righteous saw him as the Son of God. Only if you are the pure in heart will you see God, and also in a lesser degree will you be able to see the 'God' or good in man and love him because of the goodness you see in him. Mark well that person who criticizes and maligns the man of God or the Lord's anointed leaders in his Church. Such a one speaks from an impure heart."
6. Blessed are the Merciful
"Our salvation rests upon the mercy we show to others. Unkind and cruel words, or wanton acts of cruelty toward man or beast, even though in seeming retaliation, disqualify the perpetrator in his claims for mercy when he has need of mercy in the day of judgement before earthly or heavenly tribunals. Is there one who has never been wounded by the slander of another whom he thought to be his friend? Do you remember the struggle you had to refrain from retribution? Blessed are all you who are merciful for you shall obtain mercy!"
7. Blessed Are the Peacemakers
"Peacemakers shall be called the children of God. The troublemaker, the striker against law and order, the leader of the mob, the law-breakers are prompted by motives of evil and unless they desist will be known as the children of Satan rather than God. Withhold yourselves from him who would cause disquieting doubts by making light of sacred things for he seeks not for peace but to spread confusion. That one who is quarrelsome or contentious and whose arguments are for other purposes than to resolve the truth is violating a fundamental principle laid down by the Master as an essential in the building of a full rich life. 'Peace and goodwill to men on earth' was the angel song that heralded the birth of the Prince of Peace."
8. Blessed Are They Which Are Persecuted
"May youth everywhere remember that warning when you are hissed and scoffed because you refuse to compromise your standards of abstinence, honesty and morality in order to win the applause of the crowd. If you stand firmly for the right despite the jeers of the crowd or even physical violence, you shall be crowned with the blessedness of eternal joy. Who knows but that again in our day some of the saints or even apostles, as in former days, may be required to give their lives in defense of the truth? If that time should come, God grant they would not fail!"
9. Continuing Efforts to Acquire the Attributes of God
This was an interesting exercise. It put a unique reading to the "Blessed Attitudes".
