Everyone is familiar with solitude of the body. We go away and sit by ourselves in a room or cave or tell the people we are living with, that we want to be left alone.
People usually like that sort of solitude for short periods.
If this aloneness is maintained, it is often due to people not being able to get along with others or being afraid of them because there isn't enough love in their own hearts. Often there may be a feeling of loneliness, which is detrimental to solitude. Loneliness is a negative state of mind in which one feels bereft of companionship. When one lives in a family or community, it is sometimes difficult to find physical solitude, it's not even very practical. But physical solitude is not the only kind of aloneness there is.
