Buddhism's Dynamic Theory of 'Self'.
Master Dogen famously said that 'to study the buddha-way is to study the self. To study the self is to forget the self. To forget the self is to be actualised by every single thing'. So what constitutes 'self' is very important in his teachings, as it is in other perspectives and philosophies. The Buddhist theory of self is called paṭicca-samuppāda in Pali, which is generally translated as 'dependent origination'. Dependent origination presents a twelve-fold chain of stages whereby things come into being interdependent with everything else. The theory itself is quite detailed, but the Buddha summed it up like this: When there is this, that is. With the arising of this, that arises. When this is not, neither is that. With the cessation of this, that ceases . Basically, dependent origination points to the fact that our sense of self arises (or doesn't!) with every single thing in our experience - what we are perceiving here and now, and what we are thinking...
