Socially and culturally, the knowledge of our own capacity for self-creation is a fulcrum, the differentiator between two stages of development.
Thanks to science and the discovery of neuroplasticity, we know that we can train our brains. This a matter of empirical fact, not opinion. Thanks to the contemplative traditions, we know how to train our minds. The knowledge that we are doing so all the time whether we like it or not – in other words, that we are always active agents in our own self-creation – can be felt to confer a deeper sense of moral responsibility (as well as power). It is a new freedom and a new burden, depending on how we relate to it.
