This is probably the most often quoted phrase from the Zen tradition:
To study the Way is to study the self.
To study the self is to forget the self.
To forget the self is to be enlightened by all things.
To be enlightened by all things is to remove the barriers between one’s self and others.
The first that comes up for me is the simplicity and clarity in it.
First, we study the apparent self – or rather our sense of self. And we can do this through for instance sitting practice, allowing the mind to bring itself into awareness, and/or inquiry – such as Big Mind, Byron Katie’s inquiries, Headlessness or Atma Vichara.
Then, we realize that the whole sense of self comes from something as simple as a belief in the idea of I. We have glimpses of selflessness, and then emerge more stably into a realization of selflessness. We forget the self by seeing what is really true in our own immediate experience, and this allows the belief in the idea of I to fall away.
The whole world is now revealed as the play of God. Everywhere and nowhere is I. It is Big Mind awakening to itself, while functionally connected with a human self.
And in this, there is no I and Other. No barriers.
Diving into self-centeredness
To do this, we need to fully dive into self-centeredness.
As long as there is a belief in the idea of I, there is a natural and unavoidable self-centeredness.
There is a belief in the idea of I, this is out of alignment with our own (unnoticed) immediate experience, so attention naturally goes to this sense of I. Whenever something is out of alignment, attention goes there to allow it into awareness and resolution.
Typically, this process takes the form of self-protection and functioning with a limited circle of care and concern.
If we dive into it more fully, with intention and some skills, it can unfold into realization of selflessness.
Studying the self
Studying the self can be seen in two ways in this context.
One is studying the sense of I, wherever it is applied. The belief in the idea of I, which creates the whole I – Other dynamic and the identification with a segment of what is. This is the one that leads to a realization of selflessness.
The other is the more conventional study of the self, in this case meaning our human self. How does it function? What are the processes? How can we allow it to heal and mature? How can we fine tune this instrument in the world of form? This is an exploration that takes place before and after realization of selflessness. Nothing changes except the context – first within the context of a sense of self, then within the context of realized selflessness.
Some approaches focus mainly on one of these. For instance, Headlessness and Atma Vichara emphasize mainly the exploration of selflessness.
And other approaches include both. For instance the Big Mind process and Byron Katie’s inquiry process. Both of these allow us to study in finely tuned detail how our human self function, allowing knots to unravel and the human self to mature and function more effectively. And they also bring us to a realization of selflessness. Elegantly, through the same process. Two birds killed with one stone.
If we only focus on realizing selflessness, we may have Big Mind awakened to itself, but functioning through a relatively undeveloped and unhealthy human self.
If we only focus on the human self, we may have a relatively healthy and mature human self, but there is still the inherent dissatisfaction from a sense of separation.
With both, we can function within a context of selflessness, also also allow our human self to continue to mature, develop, heal and explore news ways of functioning in the world of form.
