People use the words “beginning” and “end” to describe the start and end of things. However, “beginning” is really the event of coming together when energy gathers, and “end” is simply the dissolution of that energy. That which came together can easily dissolve if conditions become unfavourable. That which has dissolved may come together again if circumstances are appropriate. Therefore, who is to say that there is a beginning and an end?
