Now, going a little higher, we come to the word "birth" (jati). In everyday language, the word "birth" refers to physically coming into the world from the mother's womb. A person is born physically only once. Having been born, one lives in the world until one dies and enters the coffin. Physical birth happens to each of us only once. This birth from the mother's womb is what is meant by "birth" in everyday language.
In Dhamma language, the word "birth" refers to the birth of the idea "I" or "ego" that arises in the mind throughout each day. In this sense, the ordinary person is born very often, time and time again; a more developed person is born less frequently; a person well advanced in practice (ariyan, noble one) is born less frequently still, and ultimately ceases being born altogether. Each arising in the mind of the idea of "I" in one form or another is called a "birth." Thus, birth can take place many times over in a single day. As soon as one starts thinking like an animal, one is born as an animal in that same moment. To think like a human being is to be born a human being. To think like a celestial being is to be born a celestial being. Life, the individual, pleasure and pain, and the rest-all these were identified by the Buddha as simply momentary states of consciousness. So the word "birth" means in Dhamma language the arising of the idea of "I" or "me", and not, as in everyday language, physical birth from the mother's womb.
The word "birth" is very common in the Buddha's discourses. When he was speaking of everyday things, he used the word "birth" with its everyday meaning. But when he was expounding Higher Dhamma - for instance, when discussing conditioned arising (paticca-samuppada) - he used the word "birth" (jati) with the meaning it has in Dhamma language. In his description of conditioned arising, he wasn't talking about physical birth. He was talking about the birth of attachment to the ideas of "me" and "mine", "myself" and "my own."
