When people fall in love, they have a magic feeling. Much of our poetry, literature and many of the movies are of the category "romance" which involves this major component of falling in love. This is one of the closest places where humans in practice experience spirituality. Of course, many of you and your cultures know very well the feeling of falling in love and you know better than we do the spiritual mechanics of the process. I will briefly describe the specifics of human experience. Falling in love for the first time happens to humans for the first time very frequently in teenager age. At that age they are still associated with parents but often feel that their path and emerging culture of their new generation is departing from the path and culture of their parents. This in part creates a feeling of separation and loneliness. Many if not most teenagers are in the state of much confusion, they know very little of life and culture around them. As most grow in mainstream culture, they have a feeling of living only once, and teen age is where they just prepare to enter adult life and act on their own. So there is a feeling of doing adult things for the first time, that is, there is a feeling of learning from scratch.
Falling in love usually happens between a boy and a girl. It may or may not involve real physicality. Often in their imagination, the teenagers go very far sexually, but in reality they may not even touch or talk about sex to each other. It depends and doesn't matter that much for the feeling. Involvement of physical sex depends much on the culture and varies much even within Western culture. Generally, teenage love involves kissing. Kissing is greatly encouraged by most human cultures. It is common between humans and animals. Kissing allows humans to physiologically interact and test each other's compatibility in a biological sense. Very often an individual would be kissing many mates, and would have romance with many mates before finalizing their choice. Again kissing and the number of trials are not that essential for the feeling. People can get a feeling without relation with the kissing and past history of romances.
The feeling of love is usually a much more intense feeling than person felt before that. The feeling of love often brings much happiness. Almost as a rule the happiness oscillates with mental pain and sadness, but happiness is what is most characteristic in the feeling of falling in love. Presence of the mate is not necessary to experience the feeling. Only a thought, only focusing the attention on the mate is usually sufficient to get the feeling of love. Sexual feeling sometimes goes together with feeling of love but in most cases these are correlated by different processes.
Learning from scratch, experiencing love for the first time is the most essential part in falling in love. Falling in love often radically changes a person and this is called having a crush. Very often the intensity of the love is asymmetrical; one person gives more love to another than receives it. In a large proportion of cases this is still a fair and healthy duet.
A part of a crush is learning much about your partner and yourself. Especially in first love, people talk much about each other and for the first time in life learn almost everything about another person and tell almost everything about themselves. This is a very healing experience. Both lovers become less lonely. Remember, that human experience involves immense loneliness since humans are generally unaware of past lives and are deaf to any communications from any spiritual beings. In teen age years, humans are often very lonely, since they mentally separate from parents; many are not well connected to peers and many have only weak friendships. So falling in love is in large extent a remedy for loneliness. Humans often understand that they are meeting a soul mate. This idea of soul mates is dominant even in Western culture. Somehow humans see it as obvious that their lovers are their soul mates. This is one of the contradictions in culture.
The love includes not only learning, talking and daydreaming, but courting, dancing, and most importantly doing things together. That is, lovers not only look at each other but also take walks and look together at the world with two pairs of eyes. This is also a unique learning experience. The lovers become empathically connected and perceive the world through their own senses and via senses and system of values of the lover.
The feeling of love is very energizing. People are at loss trying to rationalize where the energies are coming from. I believe they are coming in part from future children who want to become their children. The energies might be streaming from happy future lines where these two people make a happy family. You know better the mechanics where these warm happy energies are coming from.
