Some of the ways to explore the mechanisms of samsara…
The main mechanism of samsara is a belief in thoughts. We take thoughts as somehow inherently true, or as reflecting something inherently true in the world. We put all or most truth into one story, and take out the truth of its reversals. In this way, a sense of I and Other is created, and this sense of a separate I is usually anchored in this human self (although it could also be this alive presence, the soul level, or witnessing itself, the causal level). And from here, the whole human drama we are so familiar with unfolds… with all its excitement and also sense of something being off.
Through The Work, we can explore these beliefs directly. We notice stress, find the belief behind it, investigate it, find the truth in its reversals, and through all this, the attachment to the story tends to release.
Through the Big Mind process, we explore each voice, and see that there is no separate I inherent in any of them. We release identification with those we have been identified with, and embrace those that have been disowned, excluded through the attachment to those same beliefs and identities. They are all there, each one with its own purpose and function for this human self and its life in the world, and yet, there is no “I” inherent in any of them.
We can shift into headlessness through the headless experiments, and see that all content of awareness is just that, content of awareness. Sounds, sights, thoughts, all just content of awareness. Trees, cars, people, sensations, thoughts, all content of awareness. They are all part of the same field. It is only thoughts that say that some are “I” and others are “Other”, and these thoughts are content of awareness as well. If “I” am anything, it is what this content arises within, to and as. All content comes and goes, but what they all arise within, to and as does not. It is what time & space and all content, including that which we previously identified with, arise within, to and as.
We can use labeling practice, temporarily differentiating the field of content into sensation, sound, smell/taste, sight, and thought, which helps us see thought as just thought, and how it combines with the other portions of the field to create gestalts that seem very real and substantial when taken only at the level of gestalts.
And lots more practices as well. These are just the ones I happen to be familiar with and use right now.
