Duality is a sticky widget. Is it right or wrong? The question begs; do we avoid it?
Let's back up a bit first.
Notice that to maintain a True Mind, one must not be an observer.
To be dynamically "in this very moment" there would be no change, therefore there would be nothing to observe.
Observation depends on change.
If you are in the water, do you see the water?
You no longer see the water and do not observe it if you are in it.
In the same way I want you to apply to your experience of being in water, to being in time,
and more specifically the passage of time.
Let's consider again the objective of training the mind,
which is the teaching to this state of the True MInd which is enlightenment.
There are two parts:
1. To have discerning nature, in the absence of discernment,
2. ...as perception follows the change of form, to undergo its own change.
At this time we will only be considering the second one.
How can I relate my experience to the teaching?
Let's break it down and apply it to an experience.
Let's say that you are at the side of a road.
You see a car approaching.
The car approaches and moves past you.
Next let's apply our mind to experience this case, as relates to our practice:
...as perception follows the change of form, to undergo its own change.
Some definitions, in this context:
perception is our five senses and in this case we will say that seeing and hearing is our perception.
(Think of your senses as gates.)
Form is the object as it exsists on it's own, independant upon our perception.
(Existance is and is not relative to our experience but this topic is not being covered at this time.)
In this case we will say the the car is form.
Change is time.
Next, what does it mean to say, having perception follow change?
What does it mean to have perception change with it?
Tricky question: If perception and form are changing simultaniously how is their change noticed?
Their change is noticed with the way that we view the progression of time; past, present and future.
If we are viewing time as an experience of the past, we may perceive the car as we remember it to be.
If we are viewing time as an experience of the future, we may expect the car to move in a certain direction.
If we are viewing the car in exactly this moment in time, following the change of time with each second, then we are having perception follow the change of form, to undergo its' own change.
Both our changing perception, and the changing form change at the same moment in time, and thus change is not observed (optimally), we are then seeing the car as it really is, in this moment in time and our mind is without boundry!
Note: Without boundry is that there is no restriction.
To be boundless is an experience of going beyond restriction.
There is the posibility that some will say that if there is no restriction
then there must be resistriction, that is a topic for later discussion.
At this time we are just introducing
the infomation at an intermediate level of training.
Restriction/no restriction is indeed still duality
none the less, this is a journey and a destination.
Time, past, present and future, and all that is the car, is a manifestation of your thought about your time with a car.
Take a moment to experience how it feels to have your perception follow the change of form, to undergo its' own change, each simultaneously.
This is meditation and integral in our meditation at our zendo.
We can see that we are truely in this moment if we no longer perceive change, even if only for a second, not by means of our ignorance or ignoring, but by means of skill in that we can be boundless and we can manifest the ability to have perception follow the change of form, to undergo its own change.
So what is the benefit of boundlessness?
The benefit is the option to have liberation from judgment, liberation from duality, from birth and death, etc.
When applied as a skillful interaction with beings, this liberation allows our boundlessness to have acceptance, to be flexible, to be patient and tolerate difficult things, and to have unconditional loving kindness, which is compassion.
