The "bond of love" originates from the thoughts in the "soul imprint", which is "love", which is accumulated after countless encounters, sharing and separations of different living beings. For example, the number of encounters between Soul Drop A and Soul Drop B in previous lives is 1000, and the number of encounters between Soul Drop A and Soul Drop C is 100 times. In this life, when Soul Drop A wishes to meet Soul Drop B, there will be more thoughts than Soul Drop A wishes to meet Soul Drop C. To put it simply, Soul Drop A wants to meet Soul Drop B in this life, and wants to stay with Soul Drop B for a longer time in this life, while Soul Drop A also wants to meet Soul Drop C but stay with each other for a shorter time. This is the relationship between people, thick and thin. If these soul droplets are human, and soul droplet A becomes human A, when he encounters soul droplet B and soul droplet C into human C in this life, human A will want to fall in love with human B or form a couple, and he will become good friends with human C. The depth of the fate bond between a person and a person lies in the fact that they meet in the same time and space in this life due to the thoughts of the previous life, if their souls can be moved by each other at the moment of intersection, and they can treat each other kindly, and their fate bond will be closer. On the other hand, if they treat each other badly, as long as neither of them wants to meet in the next life, then their bond will be broken. But the most frustrating thing is to treat each other badly, but one party does not want to let go, follows the other party, and wants to meet again in the next life, their fate bond will not be broken, but may become enemies or resentful couples in the next life. In fact, the process of returning the "Soul Droplet" to its original source, the "Star Soul Ocean", and then turning into a soul droplet and putting it into this life is quite complicated, so the fate between people and between people and other living beings is also complicated.

In addition to RNA and DNA, the evolution of life forms is also driven by the "bond of love" between living beings. There are various forms of reunion between living beings in this life because of the "bond of love" with each other, and eating and being eaten are only one of them, and the other forms of reunion have promoted the evolution of life forms. Sustaining life is not just a constant duplication of instructions, instructions, and instructions hidden in the DNA of the "star", but also the meaning of life, the desire to be born, and the desire to pursue happiness. It would be wrong to think that the evolution of DNA is the ultimate evolution of the "life program", and "love" is the key to the evolution of the "life program" of DNA.

The first level of reunion is the meeting of the water: starting from the lowest creatures, if there is a bacterium that is the simplest of lifeforms, it will only absorb nutrients from the sun and water to survive, and does not need to "eat" other life forms to sustain its own life. This kind of bacteria mainly follows the life process of DNA to continue its life, that is, it is a single cell that reproduces and continues life through self-division, and the "fate bond" between bacteria and bacteria formed by "love" is simply met in the same time and space, that is, bacteria A happens to be next to bacteria B, or bacteria A is divided into two and turns into bacteria C and bacteria D.

The second level of reunion is the relationship between "eating" and "being eaten"..In the coming of this life, bacteria A will change into other life forms and become a higher creature, whether this creature can "eat" bacteria, or call him a bacterium A, because he has shared the experience of life in the previous life, and has a "longing" with bacteria B, bacteria C and bacteria D, this "missing" will directly make them reunite in this life, but the form of reunion is ever-changing, and the most basic is the relationship between "eating" and "being eaten". Bacteria A, who can "eat", will meet bacteria B, bacteria C, and bacteria D in the way of "eating" in this life, and give them "food" or "eat" them.

The third level of reunion is the exchange of DNA: as life evolves further, as organisms share more life experiences with each other, the pattern of encounters between living beings changes. Because of "missing", some "soul droplets" want to stay with other "soul droplets" in this life for a longer time, or be more intimate. These "thoughts" cause living beings to generate new ways of continuing life by combining "male" and "female". This is the birth of a new life through the union of DNA between the male and female, which forms a new way of "reunion", and the reunion of the "soul droplet" in this life is no longer limited to "eating" and "being eaten", but forms a new "cooperative" relationship. The most direct example of this new form of reunion is mating between insects, where the male and female meet and mate, then separate, while the female gives birth to the baby and leaves. The reunion of male and female insects is limited to the exchange of DNA, while the reunion of small insects with male and female insects is to inherit their DNA and live in this world.

The fourth level of reunion is the mother's love, which is a further step in the evolution of creatures, such as cats. After the male and female cats mate, after the combination of DNA and the birth of a new kitten, the male cat leaves, and the mother cat herself conceives and gives birth to the kitten, but this time the mother cat does not leave, but stays to take care of the kitten until it is independent. This is a new way of "reunion", the reunion between the mother cat and the kitten is no longer limited to the inheritance of DNA, but the time spent together is increasing. It is each other's "longing" that forms a stronger "bond of fate", which is the germ of "maternal love". The benefits of this evolution are obvious, and kittens have a better chance of survival when they are cared for by their mothers, so they are more able to reproduce the species.

The fifth level of reunion is the love of man and woman, and the creatures evolve further, such as the seagull. After the male and female seagulls mate, a new baby seagull is born through the combination of DNA, and the male seagull stays behind and takes care of the baby with the female. This is a new way of "reunion", the reunion between the female seagull and the male seagull is no longer limited to the exchange of DNA, the same is the "missing" of each other to form a stronger "bond of fate", and the "love between men and women" between them is generated, and this "love between men and women" is generated by "longing" on the one hand, and on the other hand, it is also triggered by the "drive to survive", because this love makes the male seagull stay to take care of the little seagull, on the surface it seems to protect the little seagull, This allows the baby seagulls to be cared for by their parents and increases their chances of survival. But in fact, this result is only a by-product of "love between men and women", because the fundamental reason for the male seagull to stay is to stay with the female seagull for a longer time. A female seagull with a baby seagull will have less chance of survival if she has to take care of the baby gull alone, because the baby seagull will become a burden to the female seagull. Therefore, in order for the female seagull to survive and stay with the male seagull, the male seagull will stay, of course, the relationship between the male seagull and the baby seagull will develop into the principle of "father's love" and "mother's love", so it will not be discussed in detail. And the way the little seagull "reunites" with his parents is now limited to the inheritance of DNA, because when he grows up, he will live alone from his parents. The relationship between a man and a woman is not limited to "physical copulation", but also becomes a "union of souls" due to the "love between men and women" between each other, and this "union of souls" is hoped to be together for a long time, so the relationship between husband and wife is derived from the "longing" of previous generations. And this "union of souls" is not only for the purpose of reproducing the next generation, they want to experience life together in this life, so even if they do not give birth to the next generation, the man and woman will still be together after the union.

The sixth level of reunion is the germ of filial piety..The "love between men and women" is also developed among animals, and some animals will stay together for a lifetime. But what goes further than animals is not the "love between men and women", but the germ of "filial piety". Because the human body structure is more fragile than that of ordinary animals, and the growth period is also very long, it requires long-term care from parents to become an adult. Therefore, "love between men and women" is a solid foundation for raising human beings, but this kind of parents devote their life force to raising children for a long time, and because children grow up for a long time, in the long growth time, the reunion relationship between children and parents is no longer limited to the inheritance of DNA, but this long-term stay together makes children and parents have new "thoughts" and stronger "fate bonds". When the child grows up, he will not leave, but will stay with his parents until he finds the other half of his life, but when the child grows up to be a young man and gets married, he will take care of his or her older parents until his parents leave the world, but he still misses his parents often in his heart. The difference between humans and animals in general is that "love" is deeper. The greatest benefit of this new "reunion" model is the inheritance of a favorable culture, as children can learn a lot of knowledge and methods from their parents when they are growing up, and when their parents are old, children will live with their parents or stay in constant contact with them, and their parents' life experiences may have a subtle impact on their children. When parents are young, they can share their growth experience with their children, and when their children get married, they can also pass on their parents' own experience in raising children to their adult children. When parents are old, the life insights they gain from looking back on the gains and losses of their lives can also be passed on to their children who are about to grow old. The "filial piety" of children to their parents is actually the most glorious kind of "love" in human evolution.

In summary, the germ of "love" is "longing", and the earliest is the reunion of "meeting in the water", and the reunion of "sacrificing one's own flesh" (i.e., eating and being eaten) is further reunited; further is "motherly love"; Further, it is the reunion of "men and women", that is, "love between men and women"; The next step is "paternal love"; Finally, there is the "filial piety" of "children to their parents". As a human being, you can experience all the above-mentioned kinds of "love", and in the course of life, the people or other creatures who pass by you every day will reunite with you in this time and space; Every day when you eat, countless living beings sacrifice themselves to fulfill your life and continue your life, which is the love of "sacrifice"; Finding your other half in the sea of people, and then getting to know each other, this is the love between men and women; When giving birth to children, invest your life force and share your own life experience with your children, which is "mother's love" and "father's love". And the relationship between parents and children for a lifetime, and children learn how to love your own children from the parents who love you, this is the love of "filial piety".
