We were discussing the unitive and the dualistic principles. Human consciousness, perception, and experience are generally geared to the dualistic principle. This means that everything is perceived in opposites — good or bad, desirable or undesirable, life or death. As long as humanity lives in this dualism, conflict and unhappiness must persist.
All who fulfill themselves contribute something to life. They enrich life not merely by using their vocational abilities but also through their ability to relate to other human beings and have fruitful contacts with them. As self-development proceeds, barriers fall; fear of others, and fear of oneself in connection with others vanishes, and therefore true relatedness becomes possible.
Let us first define the difference. In sadness you accept without self-pity a painful fact of life as something beyond your power to change. When you are truly sad, without depression, you not only feel it as a healthy growing pain free of hopelessness, but you are sad due to an outer circumstance, knowing it is going to pass. There is no superimposition, no hiding, no shifting of emotions. In depression the outer circumstance may be the same, but your feelings of pain are, to quite an extent, due to other reasons than the outer occurrence.
