It is neither possible nor desirable for the Universal House of Justice to set forth a set of rules covering every situation. Rather is it the task of the individual believer to determine, according to his own prayerful understanding of the Writings, precisely what his course of conduct should be in relation to situations which he encounters in his daily life. If he is to fulfil his true mission in life as a follower of the Blessed Perfection, he will pattern his life according to the Teachings. The believer cannot attain this objective merely by living according to a set of rigid regulations. When his life is oriented toward service to Bahá'u'lláh, and when every conscious act is performed within this frame of reference, he will not fail to achieve the true purpose of his life.

Therefore, every believer must continually study the sacred Writings and the instructions of the beloved Guardian, striving always to attain a new and better understanding of their import to him and to his society. He should pray fervently for Divine Guidance, wisdom and strength to do what is pleasing to God, and to serve Him at all times and to the best of his ability.
