At the very outset of practice, arouse the aspiration to break through the mind of birth and death. With determined resolve, see through the universe, body and mind, and realize that everything is [the coming together of] provisional conditions--without a substantial self - Master Boshan, Exhortations on Investigating Chan from Sheng Yen (2006) Attaining the Way: A Guide to the Practice of Chan Buddhism, (p.7)
What exactly does it mean to "break through the mind of birth and death"? Perhaps it means a literal birth and death, but it could also mean the view of birth and death that keeps people in a cycle of bondage. When I continue to believe that I am bound to a cycle of coming into being, I am using my mind to connect the previous experiences with the present, adding to this the concept of a self that experiences and "travels" from past to present to future.
I wonder if this is what Master Boshan means by "break through the mind of birth and death". At the same time, when he says "break through", it makes me think of how sometimes the only way to see past a brick wall is to shatter it, rather than trying to carve a neat little door into it. Chan Buddhism tends to use a lot of aggressive metaphors such as "break through" or "shatter" to describe an act of sudden awakening that has to transcends the barrier of self and other.
"Breaking through", for sure, may involve some kind of superhuman strength: a resolve, a kind of willpower that pushes past distractions and discriminations. The importance of "determined resolve" here should not be underemphasized, since it entails that we should use a determined effort to counterbalance the tendency to divide the world between self and other (subject/object), which gives rise to all kinds of grasping mentalities and vexations. Wanting very much to "stay afloat" on the raft of life, we fail to realize that we are creating the sense of desperation and conflict by giving rise to (and reinforcing, for that matter) the separation of self and other. But more to the point, breaking through requires completely letting go of the safety raft of words and concepts; it entails a clean break, rather than trying to use words as crutches to support that subtle sense of self and grasping.
The concept of a clean break if followed by the notion of seeing through as in see through the universe, body and mind. What is seeing through? Does it mean to have x-ray glasses that see through everything magically? I think not. It means to be able to see all phenomena as having an empty, dependently originating nature. It is to see that body, universe, mind--all the things we distinguish as separate entities--are in act interconnected parts. The notion of separation is only a conceptual one and is not based on the real experience of things interconnected. Does this insight or this seeing through really require superhuman strength? Well, it requires a determination not to act from a place of routine dualism and habits.
Finally, one realizes the crux of the matter: realize that everything is [the coming together of] provisional conditions--without a substantial self . This hinges upon the three Dharma seals of emptiness, impermanence, and no-self. When we stop acting from the idea that everything is a discrete identity, then where is the sense of opposition? Let's break this down if we can:
Without a separate substantial self, is there any room for grasping the other as someone who can be possessed? Rejecting the other as someone worthy of disdain? Praising the self as something precious and immortal? Seeing success as great, failure as small? Comparing myself to others? Without a separate self, everything is seen in its fluidity. Our role becomes that of temporary players in the stream of life, rather than permanent stations. And then we can let go of the grave seriousness of having to be a complete, whole, integrated player who has everything "all together". By nature, we come into the game as passerbys: identities that are in constant learning, flux and shaping. With this full realization, we naturally will experience less grasping, comparison, desire, envy, greed, self-preservation, etc.
