Buddha-nature is not just one particular nature. It refers to many different characteristics, aspects, potentials or traits of the Buddha-family, which we all have. These will allow us to become a Buddha. Thus, when we talk about the five Buddha-families, we are actually talking about five different groups of characteristics or traits that we all have that will allow us to become a Buddha. These five traits are mental activity, good qualities, verbal expression, physical expression and influence – or body, speech, mind, qualities and activity.
