Perfection means something is complete, like yin and yang, and does not have poisonous elements. It is not obscured by poisonous fog. Perfection is neither good nor bad. It is a natural frequency.
All people have defects, but saints and sages can accept their defects. Most people dwell on their own defects. If people had a positive viewpoint like saints and sages do, then they would see perfection around them, too. Instead, most people like to think of things as “wrong” or “ a problem”, which means they are using their human mind or mind of perception.
Defects are yin and have power. To avoid seeing the defects in other people, we need to practice a lot so we do not have time to see them.
Our mind has an appetite. Love problems are problems of the mind, but not part of our practice to discipline our mind. We want to practice so our frequency is smooth. Most types of love are just an emotional movement. Using this sort of practice it is difficult to improve your elements.
