The needs in a human being have risen because of a certain sense of incompleteness. People are forming relationships to experience a certain sense of completeness within themselves. When you have a good relationship with someone dear to you, you feel complete. When you don’t have that, you feel incomplete. This life is a complete entity by itself. Why is it feeling incomplete and why is it trying to fulfill itself by making a partnership with another piece of life?
The fundamental reason is that we have not explored this life in its full depth and dimension. Though that is the basis there is a complex process of relationships as such, there are expectations, the expectations that most people are creating themselves. There is no human being on the planet, who could ever fulfill those expectations. Especially in the man-woman relationships the expectations are so much that even if you marry a god or a goddess, they will fail because the expectations are so unrealistic that nobody, no human being can ever fulfill them. If you understand what is the source of this expectations you could form a very beautiful partnership.
Fundamentally why have we sought a relationship? Because you find yourself that without a relationship you become depressed. You are seeking a relationship because you want to be happy, to be joyful or in other words you are trying to use the other as a source of your happiness. This means your happiness is not on self start. If you are happy by your own nature, relationships will become a means to express your happiness, not to seek happiness. If you have become a joy by yourself and you are forming a relationship because you want to express your happiness nobody is going to complain about you because you are in the process of expressing your joy not seeking joy from the other person. If your life becomes an expression of your joy, not a pursuit of happiness, then relationships will be naturally wonderful.
