The fruits that best befit the tree of human life are trustworthiness and godliness, truthfulness and sincerity; but greater than all, after recognition of the unity of God, praised and glorified be He, is regard for the rights that are due to one's parents. This teaching hath been mentioned in all the Books of God, and reaffirmed by the Most Exalted Pen. Consider that which the Merciful Lord hath revealed in the Qur'án, exalted are His words: "Worship ye God, join with Him no peer or likeness; and show forth kindliness and charity towards your parents..." Observe how loving-kindness to one's parents hath been linked to recognition of the one true God! Happy they who are endued with true wisdom and understanding, who see and perceive, who read and understand, and who observe that which God hath (Baha'u'llah, The Kitab-i-Aqdas)
