I was reminded of a couple of my posts from the adjacency thread starting here, copied below.
[Speaking of the Borg] resistance is not only not futile but necessary. Speaking of resistance, according to the Tai Chi Classics one can 'using four ounces to deflect a thousand pounds.' To do this one must 'distinguish clearly between substantial and insubstantial.' Both are accomplished via compression and leverage, both within one's body and by applying them to another body. Compression and leverage are accomplished by maintaining 4 ounces of resistance or pressure between them at all times and through all changes. Without this resistance our biomagnetic and biomechanical energy does not flow with enough force to move much of anything, much less a thousand pounds.This is also critical in partner dance connection/communication.
To connect it to this [adjacency] thread, the last post relates specifically to principles 1 and 10 [and 11]. For example, principle 1 is about the fundamental premise of same-difference or connective-separation. The latter pair is more suited to my purpose, as it exemplifies the relation between any 'two.' This could relate not just a philosophical axiom but practically to one person or two people (or more) in my above example. In practicing tai chi alone one is always playing with this ever-changing 'balance' between active and passive between parts of their body-mind, or substantial and insubstantial. And there are several of these balances going on at the same space-time, like between the two hands, the two feet, the head and feet, the front and back, etc. These complimentary parts are connected yet 'clearly distinguished.'
Where the resistance or pressure comes in is in the dynamic tension between them (principle 11). Note the preposition 'between.' It is what glues them together yet also keeps them apart like a generative (en)closure. I.e, they are adjacent, not one and not two, at least not exactly. This 4 ounces of resistance is strongly akin to any permeable boundary that is both open and closed, that not only separates one from another but also allows connection and communication with another. Hence the practice can also been done with another(s), which experience of working with another feeds back to working with oneself and vice-versa. The training requires both as an ongoing practice. Hence principle 10, for one is this practice is both/and/neither/nor one/two in oneself and with another.
