The Buddha’s teaching on the development of right understanding of realities is deep, it is not easy to grasp what mindfulness and right understanding are. For this reason I would like to give a further explanation of objects of mindfulness which present themselves in daily life. Some people believe that mindfulness is being conscious of what one is doing. If one is conscious of what one is doing, such as reading or walking, there is thinking of concepts, no awareness of realities. There is clinging to an idea of self who reads or walks. No matter what one is doing there are mental phenomena and physical phenomena and understanding of them can be developed. When one, for example, is watching T.V., there can be thinking of a story which is being enacted. However, there is not only thinking, there are also seeing, visible object, hearing, sound, feeling or remembrance. Most of the time there is forgetfulness of realities, there is thinking of concepts. However, in between the moments of thinking there can be mindfulness of one reality appearing through one of the six doors, an ultimate reality which is either a mental reality or a physical reality. The characteristics of different realities can gradually be learnt. When we read a book we think of the meaning of the letters and of the story. But there are also moments of seeing merely what is visible, of what appears through eye-sense. It is because of remembrance that we know the meaning of what we read. Remembrance is a mental factor arising together with the citta, it is not self. Also remembrance can be understood as it is. It seems that thinking occurs at the same time as seeing, but they are different cittas with different characteristics.The characteristics of different realities can be investigated, no matter whether we are seeing, reading, hearing or paying attention to the meaning of words. When this has been understood we will see that objects of awareness are never lacking in our daily life. There are six doorways, there are objects experienced through these six doorways and there are the realities which experience these objects. That is our life.
