God's "law" is simple: All beings are filled with God, including you. Treat all beings with love, respect, empathy and sensitivity. When you serve God's being, you serve God. See God in all - always relate from heart to heart - from soul to soul.
Strong Kaur answered well. There is an implicit assumption in your message that people have degrees of prettiness, but people find different things "pretty" such as facial symmetry, skin color, etc. That sort of social "prettiness" is temporary. Tastes change, our appearance changes, style and fashion change. These things are not about what makes someone beautiful. What makes a woman beautiful is that she is secure, relaxed, happy, graceful and kind - that she knows who she is and loves herself! The "prettiness" industry is based on making women feel insecure about their looks so they buy products. No one who has a deep and affectionate relationship with their own soul can be insecure.
What I hear behind your question is "I want someone to love me." To that I say, "how much do you love yourself?" When you meditate, do japa and paath you get closer to your soul and fall in love with the God in you (and the God in everyone!) When you deepen your relationship with your own soul and with Guru Ji, and let go of your desire to be loved, then you allow Guru Ji to to bring you the partner you are destined to be with.
